Abstract
The invention provides a wheel contact type resistor. The wheel contact type resistor comprises a round shell and a ring-shaped resistor body, wherein the ring-shaped resistor body is arranged in the round shell; a resilient sheet is arranged between the round shell and the ring-shaped resistor body; the two ends of the resilient sheet tightly press the inner wall of the round shell by a pulley a and a pulley b; the middle part of the resilient sheet tightly presses the ring-shaped resistor body by a contact wheel; the middle part of the resilient sheet is connected with an adjusting handle; the adjusting handle is connected with an output wire; the ring-shaped resistor body is connected with an input wire; the pulley a and the pulley b are insulating wheels; and the resilient sheet is made of high-elasticity copper alloy. The wheel contact type resistor has the beneficial effects of simple structure and convenience for manufacturing and using; and a contact piece is replaced with the contact wheel so that the friction between the contact piece and the resistor body is reduced, the occurrence rate of faults is greatly reduced and the wheel contact type resistor is easy to popularize.
Description
Technical field
The present invention relates to a kind of resistance, especially a kind of wheel contact 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 wheel contact resistance.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of wheel contact resistance, comprise circular housing and cast resistance, cast resistance is placed in circular housing inside, shell fragment is provided with between described circular housing and cast resistance, described shell fragment two ends compress circular housing inwall by pulley a and pulley b, compress cast resistance, connect release handle in the middle part of described shell fragment in the middle part of described shell fragment by contact wheel, described release handle connects output line, and described cast resistance connects input line.
Described pulley a and pulley b is insulation wheel.
Described shell fragment material is high-elasticity copper alloy.
The invention has the beneficial effects as follows: structure is simple, to manufacture and easy to use, use contact wheel to replace contact, decrease the friction between contact and resistance, thus greatly reduce the incidence of fault, be easy to popularization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, circular housing, 2, cast resistance, 3, shell fragment, 4, pulley a, 5, pulley b, 6, contact wheel, 7, release handle, 8, output line, 9, input line.
Embodiment
A kind of wheel contact resistance, comprise circular housing 1 and cast resistance 2, it is inner that cast resistance 2 is placed in circular housing 1, shell fragment 3 is provided with between circular housing 1 and cast resistance 2, shell fragment 3 two ends compress circular housing 1 inwall by pulley a4 and pulley b5, cast resistance 2 is compressed by contact wheel 6 in the middle part of shell fragment 3, release handle 7 is connected in the middle part of shell fragment 3, release handle 7 connects output line 8, cast resistance 2 connects input line 9, pulley a4 and pulley b5 is insulation wheel, shell fragment 6 material is high-elasticity copper alloy, structure is simple, manufacture and easy to use, contact wheel is used to replace contact, decrease the friction between contact and resistance, thus greatly reduce the incidence of fault, be easy to promote.
