Description
Technical field
The utility model relates to a kind of brake equipment, is specifically related to a kind of brake equipment of beach buggy.
Background technology
Stop mechanism on the present beach buggy is divided into handbrake mechanism and service brake mechanism, and wherein handbrake mechanism comprises the pump housing before front-wheel disc brake dish on the wheel hub mount pad that is arranged at left and right front-wheel respectively, the disc brake pincers and is fixed in parking brake operating control on the direction handle pipe.Wherein front-wheel disc brake dish is used for the braking of left and right front-wheel, and disc brake pincers front pump body is used for locking front-wheel disc brake dish, and the parking brake operating control connects the preceding pump housing of disc brake pincers by oil pipe respectively.Service brake mechanism comprises the back disc brake dish that is arranged on the rear propeller shaft, the disc brake pincers back pump housing, service brake operating control, and wherein the disc brake pincers back pump housing is used for disc brake dish after the locking, and the service brake operating control is connected with the pump housing behind the disc brake pincers by oil pipe.Beach buggy in the process of moving, with the locking of two front-wheel disc brake dishes, i.e. locking two front-wheels are to reach the braking purpose by operation parking brake operating control; Will back disc brake dish locking by operation service brake operating control, i.e. locking rear propeller shaft, the two trailing wheels locking immediately that links with it by the back axle casing under the situation of rear propeller shaft locking reaches the purpose of braking rear-wheel simultaneously.Because the power of beach buggy is bridge before and after passing to from driving engine by transmission shaft, finally distributes to front and rear wheel driving front and rear wheel by forward and backward bridge and rotates (being 4 wheel driven) synchronously.But the control of the parking brake operating control of above-mentioned stop mechanism is only braked two front-wheels, and the service brake operating control is only braked two trailing wheels.When only handbrake mechanism being operated separately, the back axle transmission device also is in running state; When perhaps only service brake mechanism being operated separately, the propons transmission device also is in running state, therefore, has only simultaneously parking brake operating control and service brake operating control are operated, and could brake front and rear wheel in the relatively short time.Otherwise, carry out parking brake or service brake brake operating separately after beach buggy still can continue the larger distance of travelling, cause brake time and distance long, the safety traffic accident takes place easily.
Summary of the invention
The utility model purpose is, a kind of brake equipment of beach buggy is provided, its only with hand stop operating control or service brake operating control, can brake front and rear wheel simultaneously, it is short to have braking time, the advantage that braking safety is high, and can under various road conditions, brake.
The purpose of this utility model is achieved in that and comprises that being used on the wheel hub mount pad that is arranged at left and right front-wheel respectively brake the front-wheel disc brake dish of left and right front-wheel, be used for the pump housing before the disc brake pincers of locking front-wheel disc brake dish, be fixed in the parking brake operating control on the direction handle pipe, and service brake operating control, the Hydraulic Pump of parking brake operating control connects a precursor diverter by oil pipe, and this precursor diverter is communicated with the preceding pump housing of left and right disc brake pincers by oil pipe respectively; The Hydraulic Pump output port of service brake operating control is communicated with a service brake diverter, this service brake diverter is communicated with precursor diverter and back body diverter by oil pipe respectively, back body diverter clamps the back pump housing by the disc brake that oil pipe is communicated with the locking trailing wheel disc brake dish that is positioned on the left and right trailing wheel respectively, is respectively equipped with the trailing wheel disc brake dish that is used to brake left and right trailing wheel on the wheel hub mount pad of described left and right trailing wheel.
Further scheme of the present utility model is: described precursor diverter is a four-way connection with four diversion port, and back body diverter is a T-pipe joint with three diversion port.
Described service brake diverter is a joint that has three diversion port at least, and the Hydraulic Pump of this service brake diverter and service brake operating control is one-body molded.
The power of beach buggy is bridge before and after passing to from driving engine by transmission shaft, finally distributes to front and back wheel by the front and back bridge.Adopted such scheme, the Hydraulic Pump of parking brake operating control connects a precursor diverter and the preceding pump housing of left and right disc brake pincers by oil pipe, the Hydraulic Pump output port of service brake operating control is communicated with a service brake diverter, this service brake diverter is communicated with precursor diverter and back body diverter by oil pipe respectively, and back body diverter is communicated with respectively by oil pipe and is positioned on the left and right trailing wheel pump housing and trailing wheel disc brake dish behind the disc brake pincers.When operating with the parking brake operating control, the hydraulic oil in the Hydraulic Pump flows into precursor diverter and back body diverter along oil pipe respectively under the thrust of piston.The hydraulic oil that flows into the precursor diverter is assigned to the preceding pump housing of disc brake pincers and the disc brake pincers back pump housing that is positioned on the left and right front-wheel again, before the disc brake pincers pump housing under the driving of hydraulic oil by two friction linings on the caliper with the locking of front-wheel disc brake dish, by front-wheel disc brake dish locking two front-wheels, to two front wheel brake; The hydraulic oil of back body diverter is along the oil pipe inflow disc brake pincers back pump housing simultaneously, and disc brake dish after the friction lining locking on the hydraulic oil driving caliper in the pump housing of disc brake pincers back by two trailing wheels after the disc brake dish locking of back, is braked two trailing wheels.When operating with the service brake operating control, pedal makes that piston is subjected to displacement in the Hydraulic Pump pump, the hydraulic pressure of whole device oil pipe pipeline raises, piston in four disc brake pincers on the front and rear wheel is distinguished locking by friction lining to four disc brake dishes under the driving of hydraulic oil, because the disc brake dish is dead by front wheel hub mount pad relative fixed before two front-wheels and two, so the disc brake dish is locking two front-wheels before the locking two in advancing, and two front-wheels are braked; Then the disc brake dish is at the back two-wheeled disc brake dish to be installed separately, and the disc brake dish is the locking trailing wheel after the locking in traveling process, and the back front-wheel is braked.
Therefore, the utility model can be braked front and rear wheel simultaneously with parking brake operating control or service brake operating control, can prevent that beach buggy from sailing larger distance carrying out follow-up the continuing of brake operating, makes the braking time of beach buggy shorten dramatically, it is short to have braking time, the advantage that braking safety is high.Certainly, if use parking brake operating control and service brake operating control simultaneously, braking effect can be better.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
