Abstract
The utility model discloses an electromagnetic braking device, which is composed of a shell and a brake shaft. The utility model is characterized in that: a braking disc is connected on the brake shaft and can move along the axial direction; one side of the shell is provided with a magnetosheath; a loop is fixed between the braking disc and the magnetosheath; through the switching on and off of the loop, the braking disc is contacted and rubs the braking surface of the magnetosheath, thus making a motor connected with the brake shaft reduce inertial motion to ensure that a clutch control system is characterized in by high quality clutch operational capacity, high starting quality and shift quality of motor vehicles and simple structure.
Description
One, technical field
The utility model belongs to self-propelled vehicle automatic Transmissions Technique field, especially relates to a kind of electro-magnetic braking device of the configuration hand-operated transmission being implemented the electrical motor of automatic clutch or automatic speed changing transformation.
Two, background technology
The transformation of enforcement automatic speed changing relates to automobile clutch is carried out effectively, controls accurately on the hand gear self-propelled vehicle, the characteristics that adopt electrical motor to be at the bottom of the clutch control device of power has a cost, to be easy to dispose, the common DC motor load current is big, outage back inertia is big, control circuit is difficult to it is implemented accurate starting and stopping, and self-propelled vehicle is very responsive to the workmanship of power-transfer clutch in when starting, has slightly out of controlly will cause self-propelled vehicle " to stop working " or impact.
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of clutch for clutch control mechanism that makes to possess special quality clutch operating ability, self-propelled vehicle starting quality and shift quality height, power-transfer clutch electro-magnetic braking device simple in structure.
Of the present utility model from be to realize like this, a kind of electro-magnetic braking device, form by brake axle and housing, be characterized in brake axle by bearing fixing on a side of housing, brake axle is connected by spline with brake disc, brake disc can be with brake axle rotation synchronously and can moving axially along brake axle, opposite side in the housing is fixed with magnetosheath, the face that magnetosheath is relative with brake disc is a brake surface, coil stationary is installed between magnetosheath and the brake disc, is provided with spring between brake disc and magnetosheath bottom surface, the brake surface of spring brake disc and magnetosheath when state of nature, all gapped between the bottom surface, brake disc, magnetosheath is that permeability magnetic material is made, and housing is that non-magnet material is made.
In order further to realize the purpose of this utility model, can also be that the gap between brake disc and magnetosheath bottom surface should be more than or equal to the gap between brake disc and magnetosheath brake surface.
The utility model and one has technology to compare and has following distinguishing feature and good effect: the utility model is that brake axle and brake disc link together, brake disc can and can move axially along brake axle with brake axle rotation synchronously, opposite side in the housing is fixed with magnetosheath, the face that magnetosheath is relative with brake disc is a brake surface, coil stationary is installed between magnetosheath and the brake disc, be provided with spring between braking sleeve and magnetosheath bottom surface, the brake surface of spring brake disc and magnetosheath when state of nature, all gapped between the bottom surface, when the electrical motor outage still is in the inertia rotation, coil electricity produces magnetic force, with brake disc pull to magnetosheath and with the brake surface friction of fitting, thereby make brake disc, axle and electrical motor stop operating, reduce the inertia of electrical motor, improved the workmanship of power-transfer clutch.
Four, description of drawings
Below in conjunction with drawings and Examples the utility model is described in further details.
Fig. 1 is a kind of structural representation of the present utility model
Five, specific embodiments
Embodiment 1, a kind of electro-magnetic braking device, with reference to Fig. 1, be that brake axle 1 is fixed on the side of housing 1 by bearing 2, brake axle 1 is rotatable, brake axle 1 and brake disc 3 are connected by spline, brake disc 3 can be with brake axle 1 rotation synchronously and can moving axially along brake axle 1, opposite side in the housing 1 is fixed with magnetosheath 5, magnetosheath 5 and brake disc 3 relative faces are brake surface 4, coil 6 is fixedly mounted between magnetosheath 5 and the brake disc 3, and be trapped among central authorities by magnetosheath 5 and brake disc 3,9 of the bottom surfaces of braking sleeve 3 and magnetosheath 5 are provided with spring 8, and spring 8 makes the brake surface 4 of brake disc 3 and magnetosheath 5 when state of nature, 9 of bottom surfaces are all gapped, the gap that brake disc 3 and magnetosheath 5 bottom surfaces are 9 should be more than or equal to the gap of 4 of brake disc 3 and magnetosheath 5 brake surfaces, the brake surface 4 that is beneficial to brake disc 3 and magnetosheath 5 is well fitted brake disc 3, magnetosheath 5 is made for permeability magnetic material, and present embodiment adopts steel, housing 7 is made for non-magnet material, and present embodiment is that aluminium is made.
When using the utility model, the power input shaft or the axle of the propulsion source-electrical motor of clutch for clutch control mechanism of clutch for clutch control mechanism can be captiveed joint with axle 1 of the present utility model, or it is the power input shaft or the axle of the propulsion source-electrical motor of clutch for clutch control mechanism of clutch for clutch control mechanism is direct as the axle 1 in the utility model, when electrical motor cuts off the power supply, when axle 1 still is in the inertia rotation, coil 6 energising work, form the magnetic force loop, magnetic force overcomes the power of spring 8, the brake disc 3 that rotates with axle 1 is pulled to fixed magnetosheath 5, brake disc 5 is fitted with the brake surface 4 of magnetosheath 5 to rub, thereby under the effect of friction force, make brake disc 3 and axle 1 braking, stop operating.
