Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, two parallel guide rails 10 are provided with between Automobile shaft 9 and the braking mechanism 12 of automobile, the utility model mainly comprises the hydraulic reservoir 1 connected successively by oil pipe, Hydraulic Pump 2, hydraulic traversing mechanism 3 and by pass valve 4, the return opening of described by pass valve 4 is communicated with by oil pipe with hydraulic reservoir 1, the outside control mouth of by pass valve 4 is connected with check valve 5 by oil pipe, the oil outlet of described check valve 5 is connected with hydraulic relief valve 6 by oil pipe, the drain tap of hydraulic relief valve 6 is all communicated with hydraulic reservoir 1 with control mouth far away, the oil outlet of hydraulic relief valve 6 is connected with hydraulic actuating cylinder drg 8 by oil pipe, described hydraulic actuating cylinder drg 8 is arranged on axletree 9, piston rod 14 line of motion of described hydraulic actuating cylinder drg 8 and guide rail parallel, piston rod 14 end is connected with cylinder sleeve 13, oil pipe between hydraulic relief valve 6 and hydraulic actuating cylinder drg 8 is provided with brake fluid pressure table 7, the movable end of described cylinder sleeve 13 is symmetrically arranged with two plectrums 11 up and down, the end of described plectrum 11 is equipped with horizontally disposed sleeve pipe 15, described two guide rail 10 correspondences are positioned at sliding block joint within two sleeve pipes 15.
In the present embodiment, described hydraulic reservoir 1, Hydraulic Pump 2 and hydraulic traversing mechanism 3 carry for automobile; Described by pass valve 4 is pilot overflow valve; Described hydraulic relief valve 6 is piloted reducer.
Automobile is when emergency braking or retarder brake, the handle of manual regulation hydraulic relief valve 6, watch the pressure data of brake fluid pressure table 7 simultaneously, hydraulic oil is crossed by pass valve 4 at the flows by action of Hydraulic Pump 2 and is finally entered hydraulic actuating cylinder drg 8 with the secondary pressure regulation effect through hydraulic relief valve 6 after check valve 5 thus promote piston rod 14 and drive cylinder sleeve 13 to move right together with guide rail 10, thus the braking mechanism 12 making plectrum 11 stir automobile makes automobile reach snap catch or retarder brake.
During automobile traveling, the handle of reverse manual regulation hydraulic relief valve 6, the oil pressure entering hydraulic actuating cylinder drg 8 reduces, and hydraulic oil returns in the drain tap hydraulic return fuel tank 1 of hydraulic relief valve 6 along former road, automobile traveling.
Because hydraulic actuating cylinder can provide larger thrust, adopt hydraulic actuating cylinder to brake respectively automobile two driving wheels, substantially increase braking effect, the brake being specially adapted to motor omnibus and heavy card automobile is for subsequent use.
The utility model structure is simple, reliable and stable, itself and main brake mechanism are independent or coordinate and brake, make full use of the hydraulic power of automobile self, do not affect the horsepower output of automotive engine, brake torque is large, all kinds of brake failure accidents that effectively can prevent motor omnibus and heavily occur in card running car.
