Description
Technical field
The present invention relates to the brake operating mechanism of trac., be specifically related to two of one of trac. brake system unit and overlap independently brake operating mechanism.
Background technology
As everyone knows, tractor braking is to be used for deceleration, sudden stop under steam, comprises Parking on the slope in the original place.Brake system is the important system of guaranteeing the trac. safety traffic, and it must guarantee: 1, good brake efficiency; 2, good brake direction steady; 3, manipulation is light, and actuating force and pedal stroke should be not excessive; 4, reliable operation; 5, braking procedure should be smooth-going, and braking force should move down steadily with pedal.
The brake system of compact tractor and part medium tractor is linkage operating mechanism at present, and the realization of namely staying the braking of (stopping) car must rely on the manipulation of service brake just to work.
Summary of the invention
The object of the invention is to: provide two of one of trac. brake system unit to overlap independently brake operating mechanism, only has a brake system unit, but service brake and to stay the braking of (stopping) car be two separate cover brake operating mechanisms, stay the braking of (stopping) car and service brake independent mutually, be independent of each other.
the present invention adopts following technical solution: through the pedal rocking arm, left brake pedal component and right brake pedal component are installed on the pedal shaft of brake system, connect brake operating mechanism through support sleeve on pedal shaft, described brake operating mechanism comprises brake axle, brake axle support soldering member, brake axle is fixed on brake axle support soldering member, it is characterized in that: through back-up ring, right brake shoe expander is installed on the brake axle right side, right cam in the middle of transition, hand braking right cam, through spacer, left brake shoe expander is installed on the left of brake axle, left cam in the middle of transition, hand braking left cam, in the middle of transition, right cam is fixed on brake axle by resilient pin, in the middle of transition, left cam triggers fixing by extension spring, connect right brake upper draw rod on right brake shoe expander, connect right drg rod assembly in the middle of transition on right cam, connect the parking brake lever assembly on hand braking right cam, connect left brake upper draw rod on left brake shoe expander, connect left drg rod assembly in the middle of transition on left cam, hand braking left cam and hand braking right cam are connected to an integral body, right cam in the middle of transition, in the middle of transition, left cam is respectively through right brake upper draw rod, left drg top rod connects the pedal rocking arm.
When right brake pedal component depresses, right brake upper draw rod drives right brake shoe expander, right brake shoe expander drives again transition when rotating in the middle of, right cam rotates, and the middle right cam rotation of transition drives drg by right drg rod assembly and rotates, thereby right braking is had an effect; When driving the rotation of parking brake lever assembly, the parking brake lever assembly drives hand braking right cam and hand braking left cam rotates, in the middle of hand braking right cam and hand braking left cam drive respectively again the middle right cam of transition and transition, left cam rotates, drive drg by right drg rod assembly and rotate, thus hand braking having an effect; When left brake pedal component depresses, left brake upper draw rod drives left brake shoe expander, left brake shoe expander drives again transition when rotating in the middle of, left cam rotates, and the middle left cam rotation of transition drives drg by left drg rod assembly and rotates, thereby left braking is had an effect; When depressing left brake pedal component, right brake pedal component simultaneously, left and right braking is illustratedly worked simultaneously by above-mentioned.
The present invention has the following advantages: 1, simple in structure, cheap, working stability, interaction between transition intermediate cam, hand braking cam and the left and right brake shoe expander of installing by the brake axle left and right sides, service brake and to stay the braking of (stopping) car be but two separate cover brake operating mechanisms in a brake system unit; 2, interact and when rotating an angle, guaranteed that service brake is not affected by it when transition intermediate cam and hand braking cam rise, also realized staying the realization of (stopping) car braking simultaneously; Interact and when rotating an angle, guaranteed to stay the braking of (stopping) car not affected by it when transition intermediate cam and left and right brake shoe expander rise, also realized the realization of service brake simultaneously; When service brake was worked, braking during standstill is action not, and braking during standstill is when working, not action of service brake, and job failure is few.3, in the middle of transition, the middle left cam of right cam and transition does not interfere with each other in course of action, can realize the effect respectively of left and right service brake.
