The utility model is employed in increases the Buffer Unit that is combined by hydraulic cylinder and spring hydraulic cylinder between vehicle bridge and the vehicle frame; Make car chassis when receiving the impact that, sudden stop poor from road conditions or violent step on the accelerator produce; This Buffer Unit can digest these impulsive forces; Make vehicle frame can not produce severe jolt, thereby improved rider's traveling comfort.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model embodiment scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1; The shock absorber that is used for car chassis of the utility model; Comprise computer controller 7, hydraulic oil pipe 3 and be fixedly connected on automotive axle 6 and vehicle frame 5 between hydraulic cylinder 2, also comprise the Buffer Unit 1 that is fixed on more than on the vehicle frame 5, an end of this Buffer Unit 1 is communicated with an end of described hydraulic oil pipe 3; The other end of hydraulic oil pipe 3 is connected with described hydraulic cylinder 2, and described computer controller 7 is electrically connected with hydraulic cylinder 2, Buffer Unit 1 respectively.
Described Buffer Unit 1 by be fixed on base plate 4 on the vehicle frame 5, with cylinder that described base plate 4 is captiveed joint in be provided with elastomeric element spring hydraulic cylinder 101, hydraulic buttery valve 102 form; One end of described hydraulic buttery valve 102 is connected with the bottom of described spring hydraulic cylinder 101 inlet; Its other end is connected with described hydraulic oil pipe 3, and hydraulic buttery valve 102 is electrically connected with described computer controller 7.
Described spring hydraulic cylinder 101 is made up of cylinder block, built-in spring 1011 and the piston 1012 of end sealing, other end opening; Built-in spring 1011 places the closed end that is positioned at cylinder body on the piston 1012; Piston 1012 and casing wall movable sealing, 1012 in the other end of cylinder body to piston is filled with hydraulic oil 1013 and links to each other with an end of described hydraulic buttery valve 102.
As shown in Figure 2, described Buffer Unit 1 is three groups, is respectively the 1st Buffer Unit the 11, the 2nd Buffer Unit 12 and the 3rd Buffer Unit 13, and the other end of its described hydraulic buttery valve 102 all is communicated with described hydraulic oil pipe 3.
The elasticity modulus of the built-in spring 1011 in described the 1st, 2,3 Buffer Units 11,12,13 diminishes successively.
