Abstract
The invention relates to a twisting resistor which comprises a ring-shaped resistor and a twisting shaft, wherein the twisting shaft is arranged in the ring-shaped resistor, and a regulating block is connected to the twisting shaft; a spring hole is formed in the middle of the regulating block, and a spring is arranged in the spring hole; the regulating block compresses the ring-shaped resistor through a contact ball, and the bottom of the contact ball compresses the top end of the spring; the ring-shaped resistor is connected with an incoming line, and the twisting shaft is connected with an output line; the contact ball is made of wear-resistant copper alloy, and the bottom end of the spring is connected with the twisting shaft. The twisting resistor has the beneficial effects of simple structure, convenience in use and low manufacture cost. The contact ball replaces a wafer, so that the service life of parts is greatly prolonged, and at the same time the incidence of failure is reduced. The twisting resistor is easy to generalize.
Description
Technical field
The present invention relates to a kind of resistance, especially a kind of twisting resistance.
Background technology
Along with the development of World Economics, the living standard of people is greatly improved, again because world energy sources is nervous and the demand of people's environmental protection, people replace automobile and motorcycle with electric motor car gradually, for meeting the demand of people, current power car manufacture is very large, a lot of electric motor car manufacturing firms is just had in China, due to the reason of technical elements, electric automobile does not also have to replace fuel-engined vehicle completely, but two take turns electric motor car has now developed into the situation that basic every household has, its production scale is huge, part very important in electric bicycle production process is exactly rheostatic speed regulation device, existing its resistance of rheostatic speed regulation device uses contact, the time used has been grown and has had wearing and tearing, thus cause the damage of rheostatic speed regulation device, larger trouble is brought to the normal use of electric bicycle, therefore the technology being badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of twisting resistance.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of twisting resistance, comprise cast resistance and twisting axle, it is inner that described twisting axle is placed in cast resistance, described twisting axle connects regulating block, is provided with spring eye in the middle part of described regulating block, described spring eye inside is provided with spring, described regulating block compresses cast resistance by contact ball, holddown spring top bottom described contact ball, described cast resistance connects input line, and described twisting axle connects output line.
Described contact ball material is wear-resistant copper alloy.
Described spring bottom end connects twisting axle.
The invention has the beneficial effects as follows: structure is simple, and easy to use, cost of manufacture is lower, use contact wheel to replace contact, substantially prolongs the useful life of part, reduce rate of breakdown simultaneously, be easy to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, cast resistance, 2, twisting axle, 3, regulating block, 4, spring eye, 5, spring, 6, contact ball, 7, input line, 8, output line.
Embodiment
A kind of twisting resistance, comprise cast resistance 1 and twisting axle 2, it is inner that twisting axle 2 is placed in cast resistance 1, and twisting axle 2 connects regulating block 3, spring eye 4 is provided with in the middle part of regulating block 3, spring eye 4 inside is provided with spring 5, and regulating block 4 compresses cast resistance 1 by contact ball 6, holddown spring 5 top bottom contact ball 6, cast resistance 1 connects input line 7, twisting axle 2 connects output line 8, and contact ball 6 material is wear-resistant copper alloy, and spring 5 bottom connects twisting axle 2.The invention has the beneficial effects as follows: structure is simple, and easy to use, cost of manufacture is lower, use contact wheel to replace contact, substantially prolongs the useful life of part, reduce rate of breakdown simultaneously, be easy to promote.
