Figure 1 shows that damping behind traditional hydraulic damping type, shown in Figure 2 is installation signal of damping on vehicle frame after this.In conjunction with Fig. 1, Fig. 2 as can be known, damping mainly is comprised of upper connection 1, lower contact 2, double barreled cylinder body 3, damping connecting rod 4, damping spring 5, oil sealing 6, guide holder 7, piston body 8, buffer spring 10 etc. after this.In upper connection 1, the lower end of double barreled cylinder body 3 and lower contact 2 weld together by nut check in the upper end of damping connecting rod 4, and the lower end of damping connecting rod 4 is stretched in the clutch release slave cylinder of double barreled cylinder body 3.Between damping connecting rod 4 and clutch release slave cylinder, be provided with piston body 8, piston body 8 is separated into upper cavity A and lower chamber B with clutch release slave cylinder, between the upper end of double barreled cylinder body 3 and damping connecting rod 4, be provided with oil sealing 6 and guide holder 7, have damping hole 8a at piston body 8 upper cavity A and lower chamber B are communicated with.The upper end of damping is hinged on the vehicle frame 18 by upper connection 1 after being somebody's turn to do, and the lower end is hinged on the back vent 19 by lower contact 2.When car ran into obstacle, damping spring 5 was compressed, and damping connecting rod 4 moves downward relatively, and the volume of lower chamber B reduces, and fluid flows to upper cavity A by damping hole 8a.Fluid flows downward when damping spring 5 restores, and is subject to resistance at fluid during by damping hole 8a, has realized the effect of damping.
Development along with rear cushion technique, damping behind the upside-down has appearred, such as State Intellectual Property Office disclosed " a kind of inverted rear shock absorber ", the patent No. is 200820099733.5, be that the upper end of damping connecting rod and upper connection 1 connect, the lower end of double barreled cylinder body links to each other with lower contact, compares damping behind traditional hydraulic damping type, its damping effect is better, and ride comfort is higher.But the common structure of damping is comparatively complicated behind the upside-down that occurs at present, and number of spare parts is many; Simultaneously, the precompression of buffer spring and damper valve plate spring is definite when design, and its precompressed damping force can only be complementary with a certain ride characteristic, can not satisfy the requirement of vehicle multi-operating mode, and its vehicle performance and travelling comfort still remain to be improved.
Summary of the invention
The present invention is directed to above-mentioned technical problem and improve, aim to provide damping behind a kind of upside-down that can regulate the precompressed damping force, with applicable different road conditions requirements, improve driving comfortability and maneuverability.
For solving above technical problem, damping behind the upside-down that a kind of precompressed damping force provided by the invention is adjustable, comprise upper connection (1), lower contact (2), double barreled cylinder body (3), damping connecting rod (4) and damping spring (5), key is: the lower end of described damping connecting rod (4) by nut check in lower contact (2), the upper end of double barreled cylinder body (3) and upper connection (1) are fixed together, the upper end of damping connecting rod (4) is stretched in the clutch release slave cylinder of double barreled cylinder body (3), and between damping connecting rod (4) and clutch release slave cylinder, be provided with piston body (8), between the lower end of double barreled cylinder body (3) and damping connecting rod (4), be provided with oil sealing (6) and guide holder (7), and guide holder (7) is positioned at the top of oil sealing (6), described piston body (8) is separated into upper cavity (A) and lower chamber (B) with clutch release slave cylinder (3b), having damping hole (8a) at described piston body (8) is communicated with upper cavity (A) and lower chamber (B), be provided with spacing pad (9) in the below of piston body (8), damping connecting rod (4) between spacing pad (9) and guide holder (7) is equipped with buffer spring (10), be provided with damper valve plate (17) and damper valve plate spring (15) between described piston body (8) and the spacing pad (9), described damper valve plate (17) covers damping hole (8a), and damper valve plate spring (15) withstands on the described damper valve plate (17); The adjusting screw (23) of the vertical positioning screwn of axis (22) and axis horizontal is housed in the described lower contact (2), the upper-end surface of described positioning screwn (22) is over against the lower end of damping connecting rod (4), after adjusting screw (23) is vertically passed the sidewall of lower contact (1), with the lower end cone tooth engagement of damping connecting rod (4).
Working procedure and principle are as follows: when car runs into jolt serious road surface and carrying capacity and increases, the precompressed damping force of damping after needing to increase, the precession adjusting screw, because adjusting screw rod and the engagement of damping connecting rod cone tooth, move up when driving the rotation of damping connecting rod, the precompression of damper valve plate spring increases, otherwise, then screw out adjusting screw, the precompression of damper valve plate spring reduces.The working principle of damping is identical behind working principle in the running process and the existing upside-down, and when car ran into obstacle, damping spring was compressed, and the damping connecting rod moves upward relatively, and the volume of upper cavity reduces, and fluid flows to lower chamber by damping hole.Fluid upwards flows when damping spring restores, and is subject to resistance at fluid during by damping hole, has realized the effect of damping.
Institute is preferably, the top of above-mentioned double barreled cylinder body (3) is installed with shoe cream room (C), bottom valve body (11) and bottom valve banking stop (16), described shoe cream room (C) is communicated with upper cavity (A) by the oil-through hole (11a) that is arranged on the bottom valve body (11), be provided with bottom valve sheet (20) and bottom valve sheet spring (21) between described bottom valve body (11) and the bottom valve banking stop (16), described bottom valve sheet (20) covers oil-through hole (11a), and bottom valve sheet spring (21) withstands on the bottom valve sheet (20).
The top of described double barreled cylinder body (3) is set with spring supporting base (12), described spring supporting base (12) links to each other with hydraulic regulation pump (14) by pipeline (13), the upper end of described damping spring (5) is against the lower surface of spring supporting base (12), and the lower end of damping spring (5) is against the upper surface of lower contact (2).When car runs into jolt serious road surface or carrying capacity and increases, can also pass through the hydraulic regulation pump, increase the interior pressure of pipeline, thereby promoting the spring supporting base moves downward, and the compression shock absorption spring, with the precompression of raising damping spring, thus the damping performance of damping after further improving.
Described damping hole (8a) is comprised of the radial hole of axial hole and through hole perpendicular to axial direction, and whole L-shaped, the optimal damping hole structure is to make things convenient for the processing of damping hole.
Beneficial effect:
(1) by sets up positioning screwn and adjusting screw in lower contact, the lower end cone tooth engagement of adjusting screw and damping connecting rod, positioning screwn carries out spacing to precession, the back-out of adjusting screw, thereby the precompressed damping force to rear damping is regulated, the user can carry out the precompression adjustment according to vehicle condition and pavement behavior, the car load damping performance is strengthened, improve adhesive quality and the Security on wheel and road surface, satisfy the requirement of vehicle multi-operating mode and people to the high request of vehicle riding comfort and maneuverability;
(2) in addition, by setting up spring supporting base, pipeline and hydraulic regulation pump, can regulate the precompression of damping spring, with the damping performance of damping after the further raising;
(2) existing upside-down damping is compared in damping behind this upside-down, and structure is more simple, compact, has effectively reduced manufacture cost.
