Description
Technical field
The utility model relates to a kind of hand-braking actuating device of trac. manual control, belongs to the Manual brake operating technical field of wheel-tire tractor.
Background technology
Traditional moving steering unit of tractor operator control is to be independent of the mechanism that pin is stepped on the cover of one outside braking more complicated, manual manual brake controlling mechanism can occupy certain space on trac., and hand braking structure often needs to be furnished with some pull bars or flexible cord is connected hand brake with stretcher, realizes that in Vehicle Driving Cycle braking has the function of braking during standstill concurrently.But need frequent braking in the Vehicle Driving Cycle process, flexible axle just can reach the failure-free braking effect because stretching needs frequent the adjusting, so use comparatively loaded down with trivial details.Secondly, be two absolute construction because manual brake operating and pin are stepped on braking, not only brake structure is complicated, and it is larger to take up room, and handles inconvenient.Moreover hand braking main steering unit generally is outsourcing device at present, so that the manufacturing cost of tractor operator brake equipment improves.
Summary of the invention
The utility model purpose provides a kind of simple for structure, compact, control comfort, flexible, and the hand-braking actuating device of the trac. manual control that takes up room little.
The utility model is that the technical scheme that achieves the above object is: a kind of hand-braking actuating device of trac. manual control, it is characterized in that: the braking treadle is provided with the hand braking seat with limiting tooth, the top that the braking treadle is positioned at hand braking seat is provided with hand braking rotating shaft, parking brake lever is connected on the side of connecting panel, the opposite side of connecting panel is hinged on the braking treadle, connecting panel is provided with the bayonet socket that joins with hand braking rotating shaft and the retaining pawl that matches with hand braking seat limiting tooth, is connected with pull back spring between retaining pawl and the parking brake lever.
The utility model is provided with the hand braking seat with limiting tooth at the braking treadle, brake simultaneously treadle and be provided with hand braking rotating shaft, the connecting panel that is connected with parking brake lever is hinged on the braking treadle, can directly parking brake lever be connected on the braking treadle, because connecting panel is provided with the bayonet socket that joins with hand braking rotating shaft and the retaining pawl that matches with hand braking seat limiting tooth, hand braking pawl when braking is connected in the limiting tooth of hand braking seat, and when brake off, hand braking pawl breaks away from the limiting tooth of hand braking seat, and hand braking rotating shaft is arranged in the bayonet socket on the connecting panel, therefore can carry out spacing to parking brake lever, compact conformation, simplified hand braking structure, brake operating is reliable.The utility model tramps with one's feet behind the pedal of lower braking treadle, then spurs parking brake lever, and the hand braking pawl on the connecting panel is connected on the limiting tooth of hand braking seat, can realize braking; And when take-off the brake, after same pin is stepped on the pedal of braking treadle, then spur parking brake lever, under the effect of pull back spring, make hand braking pawl break away from the limiting tooth of hand braking seat, can easily throw off braking, can point pull gently parking brake lever can realize the braking, flexible to operation, it is little to take up room, and the hand brake operation device can be installed in the bearing circle below.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the hand-braking actuating device of the utility model trac. manual control.
Wherein: 1-support, 2-brakes rotating shaft, and 3-brakes swing arm, 4-lever connection, the hand braking seat of 5-, 5-1-limiting tooth, 6-fastener, 7-connecting panel, 7-1-bayonet socket, 7-2-retaining pawl, the hand braking rotating shaft of 8-, 9-pull back spring, 10-parking brake lever, 11-braking treadle.
The specific embodiment
As shown in Figure 1, the hand-braking actuating device of the utility model trac. manual control, braking treadle 11 is provided with the hand braking seat 5 with limiting tooth 5-1, this limiting tooth 5-1 can adopt ratchet or helical teeth, make things convenient for retaining pawl 7-2 to be stuck on the limiting tooth 5-1, the top that braking treadle 11 is positioned at hand braking seat 5 is provided with hand braking rotating shaft 8, hand braking rotating shaft 8 horizontal brakings on the treadle 11, parking brake lever 10 is connected on the connecting panel 7, one side of connecting panel 7 is hinged on the braking treadle 11, connecting panel 7 one sides are hinged on the braking treadle 11 by fastener 6, parking brake lever 10 is connected to the opposite side of connecting panel 7 by fastener 6, connecting panel 7 is provided with the bayonet socket 7-1 that joins with hand braking rotating shaft 8 and the retaining pawl 7-2 that matches with hand braking seat 5 limiting tooth 5-1, hand braking pawl 7-2 when braking is connected in the limiting tooth 5-1 of hand braking seat 5, and when brake off, hand braking pawl 7-2 breaks away from the limiting tooth 5-1 of hand braking seat 5, because hand braking rotating shaft 8 is arranged in the bayonet socket 7-1 on the connecting panel 7, can carry out spacing to parking brake lever 10, be connected with pull back spring 9 between retaining pawl 7-2 and the parking brake lever 10, after parking brake lever 10 external force are eliminated, can make retaining pawl 7-2 throw off limiting tooth 5-1.As shown in Figure 1, the utility model lever connection 4 is connected with drg, captive joint with braking swing arm 3 by braking rotating shaft 2 in the top of braking treadle 11, braking rotating shaft 2 is hinged on the support 1, when on the pedal of pedal brake treadle 11, rotate along its line of centers by the 11 band brake rotating shafts 2 of braking treadle, namely drive braking swing arm 3 and make lever connection 4 make the drg action, and then realize pedal brake.
See Fig. 1 shown in, step on the springboard of braking treadle 11 by pin when chaufeur after, namely to A to rotation, braking treadle 11 and braking rotating shaft 2 are rotated together, and make the drg action and when reaching brake request by braking swing arm 3 and lever connection 4, pull out parking brake lever 10 with hand again, namely to B to rotation, connecting panel 7 is along its hinged center rotating, the simultaneously thorny braking rotating shaft 8 of the bayonet socket 7-1 on the connecting panel 7 is rotated, and goes up hand braking to realizing so that the retaining pawl 7-2 on the connecting panel 7 is connected to the limiting tooth 5-1 of hand braking seat 5; When the needs take-off the brake, when chaufeur is stepped on the springboard of braking treadle 11 by pin, then unclamp parking brake lever 10, under the effect of pull back spring 9, can easily throw off limiting tooth 5-1 by retaining pawl 7-2.
