Description
Technical field
The utility model relates to the brake operation mechanism of trac., is specifically related to two of a brake system unit of trac. and overlaps independently brake operation mechanism.
Background technology
As everyone knows, the trac. brake system is used for slowing down under steam, sudden stop, comprises Parking on the slope in the original place.Brake system is an important system of guaranteeing the trac. safety traffic, and it must guarantee: 1, good brake efficiency; 2, good braking direction is stable; 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 the interlock steering unit at present, and the realization of promptly staying the braking of (stopping) car must rely on the manipulation of service brake just to work.
Summary of the invention
The purpose of the utility model is: provide two of a brake system unit of trac. to overlap independently brake operation mechanism; Has only a brake system unit; But service brake and to stay the braking of (stopping) car be two separate cover brake operation mechanisms; It is independent mutually to stay braking of (stopping) car and service brake, is independent of each other.
The utility model 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 the pedal shaft; Described brake operation mechanism comprises brake axle, brake axle support soldering member, and brake axle is fixed on the brake axle support soldering member, it is characterized in that: on the brake axle right side in the middle of back-up ring is installed right brake shoe expander, transition right cam, hand braking right cam; Through spacer left brake shoe expander, the middle left cam of transition, hand braking left cam are installed in the brake axle left side; Right cam is fixed on the brake axle through resilient pin in the middle of the transition, and the middle left cam of transition triggers fixing through extension spring, connects right braking top rod on the right brake shoe expander; Connect right drg rod assembly in the middle of the transition on the right cam; Connection hand lever connection assembly on the hand braking right cam connects left side braking top rod on the left brake shoe expander, connect left drg rod assembly in the middle of the transition on the left cam; Hand braking left cam and hand braking right cam are connected to an integral body, and left cam is braked top rod through the right side respectively in the middle of right cam, the transition in the middle of the transition, left drg top rod connects the pedal rocking arm.
When right brake pedal component is stepped on following time; Right braking top rod drives right brake shoe expander; Right side brake shoe expander drives the middle right cam rotation of transition again when rotating, right cam rotation is then rotated through right drg rod assembly drive drg in the middle of the transition, thereby right side 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 rotation; Hand braking right cam and hand braking left cam drive middle right cam of transition and the middle left cam rotation of transition again respectively; Drive drg through right drg rod assembly and rotate, thus hand braking having an effect; When left brake pedal component is stepped on following time; Left side braking top rod drives left brake shoe expander; Left side brake shoe expander drives the middle left cam rotation of transition again when rotating, the middle left cam rotation of transition then drives drg through left drg rod assembly and rotates, thereby left the braking had an effect; When stepping on down simultaneously left brake pedal component, right brake pedal component, then about braking illustratedly work simultaneously by above-mentioned.
The utlity model has following advantage: 1, simple in structure; Cheap; Working stability; Mutual action between transition intermediate cam, hand braking cam and the left and right sides brake shoe expander of installing through the brake axle left and right sides, service brake and to stay the braking of (stopping) car but be two separate cover brake operation mechanisms in a brake system unit; 2, play mutual action and when rotating an angle, guaranteed that service brake is not influenced by it when transition intermediate cam and hand braking cam, also realized staying the realization of (stopping) car braking simultaneously; When transition intermediate cam and left and right brake shoe expander play mutual action and when rotating an angle, guaranteed to stay the braking of (stopping) car not influenced by it, 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, the middle left cam of right cam and transition does not disturb in course of action mutually in the middle of the transition, can realize the effect respectively of left and right service brake.
