Abstract
A parking brake pedal locking mechanism of a tractor comprises a locking pin shaft, a locking toothed plate assembly, a torsion spring, a locking toothed plate installation plate, a brake pedal return spring, a brake pedal assembly and a brake pedal shaft. The brake penal assembly is sleeved on the brake penal shaft, the locking pin shaft is installed on the brake pedal assembly, the locking toothed plate assembly is installed on the locking toothed plate installation plate, one end of the torsion spring is fixed on the locking toothed plate installation plate, the other end of the torsion spring butts against the locking toothed plate assembly, one end of the brake pedal return spring is fixed on the brake pedal assembly, and the other end of the brake pedal return spring is fixed on a tractor floor. Although the parking brake pedal locking mechanism of the tractor relates to a toothed plate rack structure, a toothed plate of the parking brake pedal locking mechanism is movable, an operation arm can be designed into appropriate length, and the parking brake pedal locking mechanism of the tractor is novel in structure, safe, reliable, effort-saving in control and easy to operate and enables the tractor to have good parking brake effect conveniently.
Description
Technical field:
The utility model belongs to the trac. field, relates to a kind of trac. stopping brake deck locking mechanism.
Background technology:
At present, the middle low power trac. of domestic production, its stopping brake deck locking mechanism mainly contains following two kinds of forms: hand braking structure and tooth plate rack structure, hand braking complicated structure, cost is also higher, generally by specialized factory, is manufactured; And the tooth plate rack structure to be generally tooth plate fix, lockout mechanism is on brake pedal, and its control arm is short, handles relatively effort.
The utility model content:
The purpose of this utility model is to provide a kind of cost lower, safe and reliable, handles laborsavingly, can effectively solve a kind of steering unit of middle low power trac. stopping brake pedal locking.
The utility model is achieved the above object by following technical scheme: trac. stopping brake deck locking mechanism comprises: locking bearing pin, locking tooth plate assembly, torque spring, locking tooth plate adapter plate, brake pedal pull back spring, brake pedal unit, brake pedal shaft; Brake pedal unit is enclosed within on brake pedal shaft, the locking bearing pin is arranged on brake pedal unit, locking tooth plate assembly is arranged on locking tooth plate adapter plate, one end of torque spring is fixed on locking tooth plate adapter plate, the other end abuts against on locking tooth plate assembly, brake pedal pull back spring one end is fixed on brake pedal unit, and the other end is fixed on the trac. floor.
The utility model can reach following beneficial effect after adopting technique scheme: although this mechanism relates to, be also tooth plate rack-and-pinion structure, its tooth plate is movable, and control arm can be designed to suitable length, novel structure, safe and reliable, handle laborsaving, easy operating.Can make easily trac. reach the good result of stopping brake.
The accompanying drawing explanation:
The main TV structure schematic diagram that Fig. 1 is the utility model trac. stopping brake deck locking mechanism disengaged condition;
The plan structure schematic diagram that Fig. 2 is the utility model trac. stopping brake deck locking mechanism disengaged condition;
The main TV structure schematic diagram that Fig. 3 is the utility model trac. stopping brake deck locking mechanism lock-out state;
The plan structure schematic diagram that Fig. 4 is the utility model trac. stopping brake deck locking mechanism lock-out state;
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Fig. 1 ~ 4, trac. stopping brake pedal locking device mainly comprises: locking bearing pin 1, locking tooth plate assembly 2, torque spring 3, locking tooth plate adapter plate 4, brake pedal pull back spring 5, brake pedal unit 6, brake pedal shaft 7.Brake pedal unit 6 is comprised of left and right two brake pedals, be enclosed within on brake pedal shaft 7, locking bearing pin 1 is arranged on brake pedal unit 6, locking tooth plate assembly 2 is arranged on locking tooth plate adapter plate 4, one end of torque spring 3 is fixed on locking tooth plate adapter plate 4, the other end abuts against on locking tooth plate assembly 2, and brake pedal pull back spring 5 one ends are fixed on brake pedal unit 6, and the other end is fixed on its correct position on trac. floor.Its Main Function is brake pedal unit 6 not to be braked get back to original position.
When using the stopping brake lockout mechanism: step on brake pedal unit 6 to certain position, then pull locking tooth plate assembly 2 and make locking bearing pin 1 engagement on its upper rack and brake pedal unit 6, reach and make
Brake pedal unit 6 is fixed on braking position.When needs start trac., unclamp locking tooth plate assembly 2, the locking bearing pin 1 on it is thrown off, at this moment with the tooth bar on locking tooth plate assembly 2, brake pedal unit 6 is got back to original position under the effect of the elastic force of brake pedal pull back spring 5, thereby has realized the function of stopping brake.This mechanism novel structure, safe and reliable, handle laborsaving, easy operating.Can make easily trac. reach the good result of stopping brake.
