Abstract
The utility model relates to a novel shock absorber, which comprises a lower steel cylinder, a shock absorption column and a piston rod sleeved inside the lower steel cylinder. A dustproof ring is arranged between the top of the lower steel cylinder and the shock absorption column. An oil seal is arranged between the dustproof ring and the shock absorption column. An aluminum alloy guide sleeve is pressed against the inner sidewall of the lower steel cylinder. The bottom of the piston rod is fixed to the lower steel cylinder through a piston rod screw. A first spring is arranged between the top of the piston rod and the top of the shock absorption column. An oil plug is arranged at the top opening of the shock absorption column. The lower end of the lower steel cylinder is equipped with a front axle tube for being connected with an axle. The novel shock absorber is good in shock absorption effect, ideal in rigidity, long in service life and relatively low in cost and is not easy to break.
Description
Technical field
The utility model relate to a kind ofly be applied to two take turns, motor tricycle, the novel damping device on electric motor car and the various vehicle.
Background technique
Various two the taking turns of circulation in the market, motor tricycle, the doffing of the vibration damper of electric motor car and various vehicles mainly is divided into two types, i.e. all aluminium alloy doffing and all steel pipe doffing.Two kinds of doffings in use respectively have defective.The insufficient strength of the doffing of all aluminium alloy is desirable, has the phenomenon of fracture to take place in the use, can cause the generation of security incident.And the aluminum alloy material cost is than higher.All steel pipe doffing cost is low relatively, but steel pipe and lining tolerance fit precision wherein are undesirable, has caused its damping performance to descend, the problem that working life is short.
The model utility content
The utility model technical problem to be solved provides a kind of novel damping device, to overcome the above-mentioned deficiency that exists in the existing technology.
The technological scheme that the utility model solves the problems of the technologies described above is following:
A kind of novel damping device; Comprise following steel cylinder, be sleeved on inner shock structure and the piston rod of said steel cylinder down; Be provided with dust ring between following steel cylinder top end and the shock structure, be provided with oil sealing between said dust ring and the shock structure, edge is pressed with the aluminum alloy guide sleeve on the madial wall of following steel cylinder; The bottom of said piston rod is fixed on down on the steel cylinder through the piston rod screw; Be provided with first spring between the top of piston rod and the shock structure top, it is stifled that the top ports place of shock structure is provided with oil, and the lower end of following steel cylinder is provided with and is used for the preceding central siphon that is connected with axletree.
Further, said piston rod is provided with piston sleeve, and the piston rod between this piston sleeve and the piston rod top is provided with second spring.
Further, the said outer side wall of steel cylinder down is provided with bracket.
The beneficial effect of the utility model is: the inner aluminum alloy guide sleeve of this device can guarantee its machining accuracy, and outside following steel cylinder can reach rigidity again and require to make its not easy-rupturing, has strengthened damping performance, long service life, and cost is relatively low.
