Abstract
The utility model provides a brake equipment of tractor, includes guide rail, brake block and strong magnet, the brake block be the vertical L type of arranging, the brake block passes through the spring to be fixed in tractor mount one side, is equipped with the horizontally spout on the mount, the one end of being close to the guide rail at the spout is fixed to the one end of spring, the other end of spring is fixed with the top of brake block, has the clearance between brake block bottom and guide rail, the strong magnet can promote brake block compression extension spring so that make the brake block along the spout remove to the direction of be close to / keeping away from the guide rail. Circular telegram / mistake electricity through the strong magnet realizes the absorption of brake block relative with it / exclude, and the normal operating of locomotive is guaranteed in clearance through keeping 3mm -5mm between spring and guide rail under the brake block normality, when the brake block received the effect compression spring of strong magnet, the friction took place with the guide rail for the bottom of brake block, realizes the speed reduction / brake to the tractor to the realization is to speed reduction / brake of traction. This brake equipment simple structure, convenient operation.
Description
Technical field
The utility model relates to the brake gear technical field of tractor truck, particularly a kind of brake gear of the tractor truck for drawing train.
Background technology
Tractor truck can as the traction power to locomotive, when locomotive operation is to needing the speed reducing locomotive to ensure the safety of locomotive operation during descending section.The control of locomotive running speed can be realized by the speed adjusting tractor truck.
Utility model content
For overcoming problems of the prior art, the utility model provides a kind of brake gear of tractor truck.
The technical scheme in the invention for solving the technical problem is: the brake gear of this kind of tractor truck, it is characterized in that: comprise two parallel guide rail, brake facing and strong magnets, described brake facing is the L shape of vertically arranging, brake facing is fixed on tractor truck fixed mount side by spring, fixed mount is provided with the chute of level, one end of spring is fixed on chute one end near guide rail, and the other end of spring and the top of brake facing are fixed, and there is gap bottom brake facing and between guide rail; Strong magnet is relative with described brake facing and be connected with power supply, strong magnet can promote brake facing compression/extension spring so that make brake facing along described chute to close/move away from the direction of guide rail; When being adjacent to guide rail bottom brake facing and guide rail rub.
Further, the gap of 3mm-5mm is had bottom described brake facing and between guide rail.
Further, described brake facing and strong magnet lay respectively at the both sides of same guide rail, and during strong magnet energising, strong magnet absorption brake facing Compress Spring also makes spring move along chute near guide rail direction, with guide rail contact friction bottom brake facing, realizes brake; During strong magnet dead electricity, spring reset promotes brake facing and automatically resets.
Further, described brake facing and strong magnet are positioned at the same side of same guide rail, the face energising that described brake facing is relative with strong magnet repels each other, when strong magnet is energized, strong magnet promotes brake facing Compress Spring and spring is moved near guide rail direction along chute, with guide rail contact friction bottom brake facing, realize brake; During strong magnet dead electricity, spring reset promotes brake facing and automatically resets.
To sum up, the beneficial effect of technique scheme of the present utility model is as follows:
Realizing the absorption/repulsion to brake facing on the other side by the energising/dead electricity of strong magnet, by keeping the gap of 3mm-5mm between spring and guide rail under brake facing normality, ensureing the normal operation of locomotive; When brake facing is subject to the effect Compress Spring of strong magnet, bottom and the guide rail of brake facing rub, and realize the deceleration/brake to tractor truck, thus realize the deceleration/brake to hauling engine.This brake device structure is simple, easy to operate.

Detailed description of the invention
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing 1-4, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
This utility model comprises two parallel guide rails 6, brake facing 5 and strong magnets 4.Described brake facing is the L shape of vertically arranging, brake facing is fixed on tractor truck fixed mount 1 side by spring.As shown in Figure 2, fixed mount is provided with the chute 3 of level, one end of spring 7 is fixed on chute one end near guide rail, and the other end of spring and the top of brake facing are fixed, and there is gap bottom brake facing and between guide rail, and gap is 3mm-5mm.
Strong magnet is relative with described brake facing and be connected with power supply, strong magnet can promote brake facing compression/extension spring so that make brake facing along described chute to close/move away from the direction of guide rail; When being adjacent to guide rail bottom brake facing and guide rail rub.
Embodiment one, as shown in Figure 1, strong magnet and brake facing lay respectively at the both sides of same guide rail, during strong magnet energising, strong magnet absorption brake facing Compress Spring also makes spring move along chute near guide rail direction, with guide rail contact friction bottom brake facing, realizes brake; During strong magnet dead electricity, spring reset promotes brake facing and automatically resets.
Embodiment two, as shown in Figure 3, described brake facing and strong magnet are positioned at the same side of same guide rail, and be all positioned at the outside of guide rail, the face energising that described brake facing is relative with strong magnet repels each other, and when strong magnet is energized, strong magnet promotes brake facing Compress Spring and spring is moved near guide rail direction along chute, with guide rail contact friction bottom brake facing, realize brake.During strong magnet dead electricity, spring reset promotes brake facing and automatically resets.
Embodiment three: as shown in Figure 4, described brake facing and strong magnet are positioned at the same side of same guide rail, and are all positioned at the inner side of guide rail, for embodiment two, this kind of arrangement more conserve space.Between two strong magnets, arrange insulation barrier 2, eliminate the application force between two strong magnets, namely a strong magnet brake facing corresponding to phase the same side works.The face energising that described brake facing is relative with strong magnet repels each other, and when strong magnet is energized, strong magnet promotes brake facing Compress Spring and spring is moved near guide rail direction along chute, with guide rail contact friction bottom brake facing, realizes brake.During strong magnet dead electricity, spring reset promotes brake facing and automatically resets.
When needs brake, start power supply, strong magnet is energized, and starts reduction of speed brake work.During power cut-off, strong magnet dead electricity,
Above-described embodiment is only the description carried out preferred implementation of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of the utility model claims.
