The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
The invention discloses a vehicle stress relieving device, which is shown in figures 2 and 3 and comprises: a hand grip 1, an adjusting rod 3 and a driving device. The hand grip 1 is used for fixedly connecting a cross member of a vehicle, of course, from the bottom side of the vehicle. The adjusting rod 3 fixes the hand grip 1; the driving device is connected with the adjusting rod 3 and drives the adjusting rod 3 to drive the gripper 1 to move up and down; the driving device comprises a speed reducing motor 12, a driving shaft group, a crankshaft 5 and a crankshaft lantern ring 4, the speed reducing motor 12 drives the crankshaft 5 to rotate through the driving shaft group, and the crankshaft lantern ring 4 is arranged at the free end of the crankshaft 5 and fixedly connected with the adjusting rod 3.
The drive shaft group includes: the device comprises a tire type coupler 11, an electromagnetic clutch, a clutch mounting seat 10, an elastic pin coupler 7 and a bearing with a seat 6; one end of the tire type coupler 11 is connected with an output shaft of the speed reducing motor 12, and the other end of the tire type coupler is connected with the electromagnetic clutch; one end of the elastic pin coupling 7 is connected with the bearing 6 with the seat, and the other end of the elastic pin coupling is connected with the electromagnetic clutch; the mounted bearing 6 is connected to the crankshaft 5.
The electromagnetic clutch includes an armature 8 and a coil 9. Through electromagnetic induction, connection and disconnection are realized, and torque can be transmitted in a connection state.
The hand grip 1 is connected to the connecting rod 3 through a hand grip connecting plate 2.
In a preferred embodiment, the vehicle stress relief apparatus of the present invention further comprises: a trench 13, the drive apparatus being provided in the trench 13, the hand grip 1 extending from the trench 13. And a bearing plate 14 is arranged at the top of the trench 13.
In another embodiment, a vehicle stress relief device, comprising: the two slope frames are arranged on two sides of the driving device respectively, and the hand grips 1 extend out of the tops of the slope frames. At least one of the sloping frames can move, and the moving direction is towards the opposite direction or the opposite direction.
As can be understood from the above two embodiments, the vehicle stress relief device of the present invention is located under the vehicle, and can be implemented in the above two ways, and when the trench 13 is used, the position of the bearing plate 14 can be adjusted to adapt to vehicles with different widths. The width adjustment can be realized by directly moving the slope frame by using the slope frame.
Taking the above example of using the trench 13 as an example, referring to fig. 3, the car passes over the vehicle strain relief device after being taken off-line. The number of the hand grips 1 is two, the hand grips 1 are in lap joint with a first cross beam of the automobile assembly, the hand grips 1 are arranged on the hand grip connecting plates 2, and the hand grips 1 can be adjusted in the Y (width) direction to adapt to automobiles with different widths. The hand grab connecting plate 2 is in threaded connection with the adjusting rod 3, the adjusting rod 3 moves up and down through rotation, the hand grab 1 and the hand grab connecting plate 2 can be adjusted in the Z (height) direction, and the hand grab connecting plate can adapt to automobiles with different heights. The lower end of the adjusting rod 3 is connected with a crankshaft lantern ring 4 through threads. It is also necessary to adjust the position in the x (length) direction, which can be moved into position by the driver's steam. Also, as shown in fig. 4, the turning radius may also provide an adjustment in the x-direction under the turning action of the crankshaft 5. Therefore, the vehicle is driven to perform rough positioning, and then fine positioning is performed by rotation of the crankshaft 5. The arrow f in fig. 4 shows the direction of rotation of the crankshaft 5.
As can be seen from fig. 3 and 4, the vehicle stress relief means of the present invention can be used in a variety of vehicle types, such as the truck of fig. 3 and the car of fig. 4.
The crankshaft lantern ring 4 is composed of two semicircles, the crankshaft lantern ring is sleeved on the crankshaft 5, and the two semicircles are connected with the crankshaft 5 and then fixed through bolts to form a whole. The crankshaft 5 is mounted on two pedestal bearings 6 about which the crankshaft 5 can rotate. Wherein, the one end of bent axle 5 is connected with elasticity pin shaft coupling 7, and elasticity pin shaft 7 is connected bent axle 5 and electromagnetic clutch, belongs to elastic connection, allows the axial to have certain deviation. The electromagnetic clutch is composed of an armature 8 and a coil 9, wherein the armature 8 and the coil 9 are attracted under the condition of power-on, and are disconnected under the condition of power-off. The two components of the electromagnetic clutch are arranged on a clutch base 10, and the clutch base 10 is precisely machined to ensure that an armature 8 and a coil 9 of the electromagnetic clutch are kept at accurate positions. The coil 9 and the speed reducing motor 12 are connected by a tire type coupling 11, and the tire type coupling 11 allows the electromagnetic clutch and the speed reducing motor 12 to have larger axial error directly, so that the smooth output of power is ensured. The gear motor 12 provides power for the whole device.
The principle of the invention is as follows: the vehicle stress relief device is powered by the gearmotor 12. The power is connected with the crankshaft 5 through the attraction of the armature 8 and the coil 9 of the electromagnetic clutch, so that the connection between the crankshaft 5 and the power is realized. After being connected with power, the crankshaft 5 rotates around the belt seat bearing 6 and can generate circular motion. The crankshaft lantern ring 4 is sleeved on the crankshaft 5 and connects the crankshaft 5 with the hand grip 1, the hand grip connecting plate 2, the connecting rod 3 and the like. The crankshaft lantern ring 4 drives the hand grip 1 and the like to perform compound motion while performing circular motion along with the crankshaft 4. The gripper 1 decomposes the compound motion to the first cross beam of the automobile, and realizes the vibration (mainly the reciprocating motion in the vertical direction) of the automobile. After the speed reducing motor 12 is powered off, the armature 8 and the coil 9 are separated at the same time, so that the crankshaft 5 is completely separated from the speed reducing motor 12, and the crankshaft 5 stops at an upper limit position (top dead center) under the action of elastic parts such as automobile tires and shock absorbers, and the separation of the gripper 1 from the automobile is facilitated.
The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
