Abstract
The invention provides a novel damper applicable to a large pressure transformation range. The damper aims at solving the problem that an existing damper is inapplicable to automobiles different in pressures. The damper comprises a first upper pressing rod, a second upper pressing rod, a first lower pressing rod and a second lower pressing rod which are distributed in a rhombus shape, wherein installation sleeves are respectively arranged at the connection positions of the upper pressing rods and the lower pressing rods, the first upper pressing rod is movably connected with the first lower pressing rod through a pin, and the second upper pressing rod is movably connected with the second lower pressing rod through a pin. The damper further comprises a connection rod, L-shaped pressing plates are respectively arranged at the upper end and the lower end of the connection rod fixedly, the two ends of the connection rod are respectively connected onto the pin between the upper pressing rods and the pin between the lower pressing rods through elastic traction parts, and damping devices are arranged between the two sides of each L-shaped pressing plate and the pressing rods. By means of multiple groups of the damping springs with different hardness and elasticity, good damping effect is achieved when the automobiles are under different pressures. The damper is novel in structure, good in damping effect, wide in application range and strong in practicability.
Description
Technical field
The invention belongs to technical field of automobile parts, particularly a kind of vapour vehicular shock absorber.
Background technique
Concussion when vibration damper is mainly used to suppress rebound after spring shock-absorbing and from the impact on road surface.When through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, therefore the harder vibration damper of the general employing of heavier car.
But, the weight of automobile is not certain, sometimes the more pressure of vibration damper carrying that will make of goods loading is larger, sometimes load the less or empty wagons of goods time vibration damper carrying pressure just less, this just allows the vibration damper of automobile be difficult to select, if select the vibration damper of harder spring will make damping effect extreme difference in empty wagons situation, if select the vibration damper of softer spring will make vehicle damping spring elastic force under load condition inadequate, do not have equally damping effect.
Summary of the invention
The object of the invention is for the deficiency of existing vibration damper and the shock damper of a kind of applicable different pressures providing.
The present invention is achieved by the following technical solution:
A kind of vibration damper, comprise the first upperpush rod that assumes diamond in shape and distribute, the second upperpush rod, the first down-pressed pole and the second down-pressed pole, joint at two upperpush rods and two down-pressed poles is equipped with installation sleeve, between the first upperpush rod and the first down-pressed pole and between the second upperpush rod and the second down-pressed pole, be all flexibly connected by pin, also comprise a connecting rod, two ends up and down at connecting rod are all connected with L shaped pressing plate, the two end part of described connecting rod are all connected on two by elastic traction part, on the pin arranging between down-pressed pole, between the both sides of L shaped pressing plate and depression bar, be equipped with damping device.
Described damping device comprises spring, guide pillar and guide pillar fitting seat, depression bar is run through in guide pillar one end, the guide pillar the other end is flexibly connected by loose pin with guide pillar fitting seat, on guide pillar, be provided with limit part, spring is arranged between the limit part and depression bar of guide pillar, and guide pillar fitting seat is fixed on L shaped pressing plate.
On described depression bar, being positioned at the position that guide pillar passes is rectangular through slot.
Be less than the hardness of the spring of the damping device between two down-pressed poles and L shaped pressing plate in the hardness of the spring of the damping device between two upperpush rods and L shaped pressing plate, and hardness and the elastic force of the spring between two upperpush rods and L shaped pressing plate equate, hardness and the elastic force of the spring between two down-pressed poles and L shaped pressing plate equates, the hardness of two elastic traction parts and elastic force equate.
Beneficial effect of the present invention: the present invention adopts the damping spring of many group different hardness and elastic force, realize car and the in the situation that of different pressures, also can there is good damping effect, in the time that the weight of car is lighter, one group of spring that the hardness of vibration damper is lower is compressed, bears alone cushioning effect; In the time that the weight of car is heavier, it is compressed that one group of less spring of hardness of vibration damper is depressed into after ultimate state one group of spring of higher hardness, two groups of spring shared cushioning effects, and elastic traction part also has certain cushioning effect simultaneously.Novel structure of the present invention, good damping effect, applied widely, practical.
