The braking device can realize the compensation of the brake clearance, ensure the braking effect and reduce the potential safety hazard.
Example one
Please refer to fig. 1 to fig. 7 in combination. This embodiment provides a brake equipment 100, and it includes shell 30, braking circle (not shown), brake (not shown), braking drive mechanism 20, arresting gear's wear compensation mechanism 10 and actuating mechanism 60, the braking circle is installed on the wheel of vehicle, brake movable mounting in on the shell 30, and correspond braking circle setting, it is specific, the brake set up in the braking circle, braking drive mechanism 20 movable mounting in on the shell 30 and correspond the brake setting is used for the drive the brake with the laminating of braking circle. The drive mechanism 60 is connected to the wear compensation mechanism 10 of the brake device for driving the oscillation of the components of the wear compensation mechanism 10 of the brake device. Arresting gear's wearing and tearing compensation mechanism 10 is used for arresting gear 100 the brake and/or brake ring takes place wearing and tearing and produces the brake clearance after, compensates the brake clearance, ensures the brake with brake ring can laminate, ensures braking effect. Specifically, the wear compensation mechanism 10 of the brake device is configured to perform angle compensation on the brake transmission mechanism 20 for driving the brake to expand outward, and when the brake device 100 is worn, the wear compensation mechanism 10 of the brake device can compensate an initial deflection angle for the brake transmission mechanism 20, so that the brake transmission mechanism 20 can rotate to a larger angle, and the brake can further expand outward to a larger distance to compensate for a brake gap. The brake can be drum brake, expansion brake, follow-up brake and the like. Through arresting gear's wearing and tearing compensation mechanism 10 makes and works as arresting gear 100 takes place the wearing and tearing back, only need stimulate the brake cable and can self-adaptation compensate to the wearing and tearing clearance, need not additionally carry out operations such as manual regulation, convenient and fast.
The wear compensation mechanism 10 of the braking device comprises an adjusting mechanism 11, a sliding seat 12 and a sliding groove 13, wherein the adjusting mechanism 11 is connected with a braking transmission mechanism 20 of the braking device and can drive the braking transmission mechanism 20 to rotate along a braking direction or a resetting direction. The braking direction refers to a direction in which when the brake actuator 20 is rotated, the brake in the brake device is caused to expand outward. The reset direction is the direction opposite to the braking direction, and specifically, when the brake actuator 20 rotates in this direction, the brake in the brake device is forced to contract inward. In this embodiment, the braking direction is clockwise in fig. 1, and the resetting direction is counterclockwise in fig. 1.
The slide 12 is disposed corresponding to the adjusting mechanism 11, and is used for limiting a swing range of the adjusting mechanism 11. That is, the carriage 12 is arranged at least in some areas in a position coinciding with the adjustment mechanism 11, the carriage 12 being partially inserted into the adjustment mechanism 11 or the adjustment mechanism 11 being partially inserted into the carriage 12. Therefore, the sliding seat 12 can limit and block the adjusting mechanism 11, so that the relative position of the adjusting mechanism 11 and the sliding seat 12 is always within a range, the adjusting mechanism 11 can only swing within a certain range in the sliding seat 12, or the sliding seat 12 can only move within a certain range in the adjusting mechanism 11.
The sliding seat 12 is installed in the sliding groove 13, the sliding groove 13 is used for limiting the sliding seat 12 to move towards the reset direction, and the adjusting mechanism 11 can drive the sliding seat 12 to move towards the braking direction in the sliding groove 13. The movement toward the reset direction means the movement along the reset direction or the movement toward the reset direction, and the movement toward the braking direction means the movement along the braking direction or the movement toward the braking direction.
Therefore, when the brake device is normal, external force is applied to enable the adjusting mechanism 11 to swing around the brake transmission mechanism 20 as a center, so that the brake transmission mechanism 20 is driven to rotate, the brake transmission mechanism 20 drives the brake to expand outwards, the brake and the brake ring are in contact friction, and braking is achieved. At this time, the adjusting mechanism 11 does not contact the slider 12, or the adjusting mechanism 11 slightly contacts the slider 12, but cannot move the slider 12 in the slide groove 13.
When a brake or a brake ring in the braking device is worn to form a brake gap, and a force is applied, the brake and the brake ring are not in contact, so that resistance cannot be generated, the movement stroke of the adjusting mechanism 11 can be increased, the adjusting mechanism 11 can swing to a larger extent along the braking direction, the adjusting mechanism 11 is in contact with the sliding seat 12 and generates driving force for the sliding seat 12, and the sliding seat 12 is urged to move towards the braking direction in the sliding groove 13. When the adjusting mechanism 11 is reset, because the sliding base 12 is restricted by the sliding groove 13 and cannot return to the initial position in the resetting direction, the sliding base 12 blocks the adjusting mechanism 11, so that the adjusting mechanism 11 cannot return to the initial position, and further the braking transmission mechanism 20 cannot return to the original angle, so that the braking transmission mechanism 20 obtains an initial deflection angle in the initial state. Therefore, during the next braking action, because the braking transmission mechanism 20 obtains a deflection angle in the initial state, after the force is applied to the adjusting mechanism 11, the braking transmission mechanism 20 can be rotated to a larger angle, the compensation of the braking clearance is realized, the braking effect is ensured, and the potential safety hazard is reduced. Meanwhile, an initial deflection angle can be provided for the brake transmission mechanism 20, so that when the brake cable has a loosening problem, the brake travel of the brake cable can be compensated, and the brake cable can brake the vehicle by only needing less travel. For example, in a normal situation, the brake cable needs 5 strokes to realize braking, and after the brake cable is loosened, the brake cable needs to be pulled for 6 strokes to complete braking. In the wear compensation mechanism 10 of the braking device provided in this embodiment, since the initial deflection angle of the braking transmission mechanism 20 can be compensated, even if the brake cable is loosened, the required rotation angle of the braking transmission mechanism 20 is reduced, so that the stroke required by the brake cable to complete braking is also reduced, and the loosened brake cable can complete braking only by pulling 5 strokes. Namely, the initial deflection angle of the brake transmission mechanism 20 is compensated, the compensation of the brake line stroke can be completed, and the brake effect of the vehicle is guaranteed.
That is, the sliding groove 13 is a one-way sliding groove, the sliding seat 12 is forced to move only toward one side of the braking direction in the sliding groove 13, and cannot move to the reset direction, so that the sliding seat 12 blocks the adjusting mechanism 11, and the braking transmission mechanism 20 is urged to obtain an initial deflection angle to compensate the abrasion loss.
In the present exemplary embodiment, the brake gear mechanism 20 is embodied as a camshaft. The sliding groove 13 is arc-shaped, so that the deflection of the adjusting mechanism 11 can be better matched. Of course, in other embodiments, the sliding groove 13 may have other shapes, and even the sliding groove 13 may be linear, that is, the sliding seat 12 only needs to be limited by the sliding groove 13, so that the sliding seat 12 can only move in one direction, and then the deflection angle compensation of the brake transmission mechanism 20 is realized.
Specifically, the brake includes two oppositely disposed brake shoes, the brake and the brake ring are mounted on one side of the housing 30, and the wear compensation mechanism 10 and the driving mechanism 60 of the braking device are mounted on the other side of the housing 30. The brake transmission mechanism 20 is movably mounted on the housing 30 and inserted between the two brake shoes, wherein the movable mounting of the brake transmission mechanism 20 on the housing 30 means that the brake transmission mechanism 20 can rotate on the housing 30 after being stressed. In the normal condition, two the outward flange of brake shoe with the brake circle is spaced each other, when needs are brakied, through actuating mechanism 60 to adjustment mechanism 11 application of force, thereby adjustment mechanism 11 drives brake drive mechanism 20 rotates, and then brake drive mechanism 20 will two the brake shoe is outside to be extrudeed, makes the brake shoe with brake circle contact friction realizes the braking effect. When the brake shoe and/or the brake ring are worn, the initial deflection angle of the brake transmission mechanism 20 can be compensated by the wear compensation mechanism 10 of the brake device, so that the wear amount of the brake shoe and/or the brake ring can be compensated by providing an initial deflection angle to the brake transmission mechanism 20.
The driving mechanism 60 includes a rocker arm 61 and a driving gear assembly 62, the rocker arm 61 is hinged to the housing 30 or the brake transmission mechanism 20, the driving gear assembly 62 is mounted on the rocker arm 61 and engaged with the adjusting mechanism 11, and the driving gear assembly 62 is used for driving the adjusting mechanism 11 to swing. The rocker arm 61 drives the driving gear component 62 to drive the adjusting mechanism 11 to swing, so that transmission is more direct, transmission efficiency is better, and the braking effect is further guaranteed.
Preferably, the sliding groove 13 includes a groove body 131 and a plurality of engaging grooves 132, and the engaging grooves 132 are disposed in the groove body 131, and a plurality of the engaging grooves 132 are sequentially disposed at intervals in the braking direction. The slide carriage 12 is at least partially engaged in one of the engaging slots 132, and the adjusting mechanism 11 can drive the slide carriage 12 to slide into another adjacent engaging slot 132 toward the braking direction. Namely, the locking slot 132 is used to block and limit the slide carriage 12, and block the slide carriage 12 from moving toward the reset direction. It will be appreciated that in this embodiment, by providing a plurality of successively spaced pockets 132, wear can be compensated for in steps until the carriage 12 slides into the last pocket 132. Through the mode of gradual compensation, can be more accurate, better compensate the wearing and tearing volume, also can avoid the compensation volume too much to lead to the too sensitive problem that influences the vehicle and normally travel of braking. It should be noted that, in the present embodiment, the card slot 132 is disposed in the slot body 131. Of course, in other embodiments, the clamping groove 132 may also be disposed outside the groove body 131, that is, only the groove body 131 needs to be disposed to guide the sliding seat 12, and the sliding seat 12 is limited by the clamping groove 132. In this embodiment, the slot 132 is disposed in the slot body 131, so that the slider 12 can be conveniently disposed, the structure of the slider 12 is simpler, and the processing and manufacturing are facilitated.
Preferably, the card slot 132 includes a bottom surface 1321, a first side surface 1322 and a second side surface 1323, wherein the first side surface 1322 is connected to one side of the bottom surface 1321, and the second side surface 1323 is connected to the other side of the bottom surface 1321. The first side surface 1322 is located at a side close to the braking direction, and the first side surface 1322 is an inclined surface. That is, the first side surface 1322 is disposed obliquely with respect to the bottom surface 1321, so that when the slide 12 is subjected to a force in the braking direction, the first side surface 1322 can guide the portion of the slide 12 located in the slot 132, so that the portion of the slide 12 located in the slot 132 can more easily enter the next adjacent slot 132. That is, by providing the first side 1322 as an inclined surface, the movement of the sliding base 12 in the sliding groove 13 is facilitated, and the force required for driving the sliding base 12 to move is reduced, so that the amount of wear can be more easily compensated.

The limiting post 122 is inserted into the limiting sliding groove 111, two side walls of the limiting sliding groove 111 are used for blocking the limiting post 122, that is, the limiting sliding groove 111 is a closed sliding groove, and two side walls (a first side wall 1111 and a second side wall 1112) of the limiting sliding groove 111 facing to the braking direction or the resetting direction can play a role of blocking the limiting post 122. The limit post 122 is limited in the limit sliding groove 111, and when the swing amplitude of the adjusting mechanism 11 increases, the limit post 122 abuts against the first side wall 1111 or the second side wall 1112, so that the adjusting mechanism 11 is blocked by the limit post 122, thereby limiting the position of the adjusting mechanism 11, or the adjusting mechanism 11 drives the sliding base 12 to move. After the braking device 100 is worn, the sliding base 12 abuts against the second side wall 1112 and is stressed to cause the elastic member 123 to deform, so that the elastic member 123 slides out of the slot 132 and slides into another adjacent slot 132 in the braking direction. In the present embodiment, the adjusting mechanism 11 is provided with the limiting sliding groove 111, and the limiting column 122 on the sliding seat 12 is inserted into the limiting sliding groove 111, so that the sliding seat 12 limits the swing position of the adjusting mechanism 11. Of course, in other embodiments, the limiting sliding groove 111 may also be disposed on the sliding seat 12, and correspondingly, the limiting column 122 may be disposed on the adjusting mechanism 11. That is, only a corresponding limit structure needs to be arranged between the adjusting mechanism 11 and the sliding seat 12 to limit the swing range of the adjusting mechanism 11 relative to the sliding seat 12, so that the sliding seat 12 is driven to move towards the braking direction and the adjusting mechanism 11 is limited to reset along the resetting direction through the contact between the adjusting mechanism 11 and the sliding seat 12. Preferably, the elastic member 123 is a metal elastic sheet, so that the elastic sheet is not easily damaged.
Preferably, the housing 121 includes a body 1211 and a mounting groove 1212 formed on the body 1211. The elastic member 123 includes a main body 1231 installed in the mounting groove 1212, and an elastic portion 1232 having one end connected to the main body 1231 and the other end engaged with the locking groove 132. By installing the main body 1231 in the installation groove 1212, the installation stability can be ensured, and the elastic member 123 can be prevented from being accidentally disengaged.
Preferably, the clamping grooves 132 are formed on both sides of the groove body 131, and the elastic portions 1232 are correspondingly disposed on the clamping grooves 132 on each side. That is, the two side walls of the groove body 131 are both provided with the locking grooves 132, the elastic portions 1232 are provided with at least two, and each of the elastic portions 1232 corresponds to one of the locking grooves 132. Through all setting up in both sides draw-in groove 132, and every side draw-in groove 132 all is provided with elasticity portion 1232, thereby make slide 12 card is located during in the spout 13, the more equilibrium of atress avoids one-way atress to take place unexpected pop out or drop, the effectual stability that has ensured.
Preferably, the seat body 121 further includes an avoiding groove 1213, the avoiding groove 1213 is formed by being recessed from a side of the body 1211 close to the slot 132 toward a direction away from the slot 132, and the avoiding groove 1213 is disposed corresponding to the elastic portion 1232. Therefore, when the elastic part 1232 is stressed to bend inwards, the avoiding groove 1213 can provide a good deformation space for the elastic part 1232, so that the sliding seat 12 can move towards the braking direction more conveniently and more easily.
Preferably, the holder body 121 further includes a limiting baffle 1214, and the limiting baffle 1214 is disposed on the body portion 1211, is disposed corresponding to the elastic element 123, and is located on a side of the bottom wall of the body portion 1211, which is far away from the slot body 131. Therefore, the elastic member 123 can be well blocked by the limiting baffle 1214, the elastic member 123 is prevented from accidentally dropping out of the sliding groove 13, the stability of the wear compensation mechanism 10 of the braking device is further ensured, and the wear compensation mechanism 10 of the braking device can compensate the wear amount.
Preferably, the driving gear assembly 62 includes a driving gear 621, a one-way bearing 622 and a mounting shaft 623, the driving gear 621 is engaged with the adjusting mechanism 11, the one-way bearing 622 is disposed inside the driving gear 621 and tightly connected to the driving gear 621, the rotatable direction of the one-way bearing 622 is along the reset direction, and the mounting shaft 623 is disposed coaxially with the driving gear 621 and the one-way bearing 622 and mounts the driving gear 621 and the one-way bearing 622 on the rocker arm 61. The one-way bearing 622 and the driving gear 621 are tightly connected, that is, the outer ring of the one-way bearing 622 and the inner side of the driving gear 621 are connected together so as to be capable of moving towards the same side, for example, the one-way bearing 622 and the driving gear 621 can adopt a structure of interference fit or key connection. It can be understood that the driving gear assembly 62 is mounted on the rocker arm 61, so that when the rocker arm 61 is driven to swing around the hinge point, the rocker arm 61 will drive the driving gear assembly 62 to swing, and the driving gear assembly 62 will drive the adjusting mechanism 11 to swing, thereby realizing the braking. Since the driving gear 621 is installed with the one-way bearing 622, and the rotatable direction of the one-way bearing 622 is along the reset direction (i.e. the counterclockwise direction shown in fig. 1), when braking normally, the driving gear 621 cannot rotate, and the driving gear 621 only abuts against the driving teeth on the adjusting mechanism 11 tightly, so as to drive the adjusting mechanism 11 to swing. When the adjusting mechanism 11 is reset after the sliding seat 12 moves in the sliding groove 13 to perform wear compensation in the wear compensation mechanism 10 of the braking device, the first side wall 1111 is in contact with the limit post 122 to be resisted and the position is limited. At this time, the driving mechanism 60 still receives a restoring force in the reset direction, so that the driving gear 621 starts to rotate in the counterclockwise direction, and the relative position between the driving gear 621 and the adjusting mechanism 11 is changed, thereby automatically adapting to the position of the wear compensation mechanism 10 of the braking device after compensation.

Compared with the prior art, the adjusting mechanism in the braking device provided by the utility model is connected with the braking transmission mechanism of the braking device and can drive the braking transmission mechanism to rotate along the braking direction or the resetting direction; the sliding seat is arranged corresponding to the adjusting mechanism and used for limiting the swinging range of the adjusting mechanism; the sliding seat is installed in the sliding groove, the sliding groove is used for limiting the sliding seat to move towards the reset direction, and the adjusting mechanism can drive the sliding seat to move towards the braking direction in the sliding groove. During normal braking operation, the brake driving is realized by applying force to the adjusting mechanism so as to drive the brake transmission mechanism to rotate; when the brake device is worn and applies force to the adjusting mechanism, the movement stroke of the adjusting mechanism is increased, so that the adjusting mechanism is in contact with the sliding seat, and the sliding seat is driven to move in the sliding groove; after the force is applied, the position of the whole sliding seat in the sliding groove moves, and the sliding seat is limited by the sliding groove and cannot be reset, so that the adjusting mechanism cannot be reset to the initial position due to the blocking of the sliding seat when being reset towards the resetting direction, and the braking transmission mechanism cannot be reset to the original angle, so that the braking transmission mechanism obtains a deflection angle in the initial state, and the compensation of the abrasion loss is realized; when the brake mechanism is in the initial state, the brake transmission mechanism obtains a deflection angle, so that the brake transmission mechanism can be rotated to a larger angle after the force is applied to the adjusting mechanism, the compensation of a brake gap is realized, the brake effect is ensured, and the potential safety hazard is reduced. Meanwhile, an initial deflection angle can be provided for the brake transmission mechanism, so that when the brake cable has a loosening problem, the brake stroke can be compensated, and the brake of the vehicle can be realized by the brake cable with less stroke.
Correspondingly, the vehicle provided by the utility model adopts the braking device, and when the braking device is worn, self-adaptive adjustment can be realized, the braking effect is effectively guaranteed, and the potential safety hazard is reduced.
