Abstract
The utility model belongs to the technical field of a subsidiary braking apparatus for heavy-duty car, in particular to an electric eddy current deceleration means for heavy-duty car use. The utility model discloses a subsidiary braking apparatus for heavy-duty car. An electric eddy current deceleration apparatus is connected with the drive shaft of the heavy-duty car, wherein the electric eddy current deceleration apparatus is composed of an automatic control circuit and a manual control circuit. The utility model can improve the performance of braking, security and amenity and prolong the service life of the braking friction piece.
Description
(1) described technical field
The utility model belongs to the technical field of heavy motor vehicle complemental brake system, the application on heavy motor vehicle slowly of particularly a kind of current vortex.
(2) background technology
At present, what the auxiliary braking system of homemade Steyr heavy motor vehicle adopted is exhaust braking, still blank for the application of other auxiliary braking system.Current vortex retarder is simple in structure, non-maintaining because of it, and particularly various road conditions can be used the advantage that can improve deceleration and stopping performance, and its application on heavy goods vehicles is a matter of time.
(3) summary of the invention
The purpose of this utility model is to provide a kind of auxiliary braking system of current vortex retarder, improves braking ability, safety, the traveling comfort of automobile, prolongs the service life of brake strip.
The utility model is realized by following measure:
The utility model discloses a kind of heavy motor vehicle complemental brake system, on the transmission shaft of heavy motor vehicle, be connected with current vortex retarder.
Heavy motor vehicle complemental brake system of the present utility model, described current vortex retarder includes automatic control circuit and manual control circuit.
Current vortex retarder circuit and control as follows:
1, when speed of a motor vehicle v＜6KM/h, 4 no-voltages outputs of retarder control unit (VD-HKD201), retarder is inoperative.
2, when vehicle velocity V 〉=6KM/h, 4 of retarder control units (VD-HKD201) have the output of 24V voltage, and retarder works.
(1) retarder manual switch: this switch slows down and the lower long slope use in long distance.
When switch was in 0 gear, 4 gears all disconnected
When switch was in 1 gear, control loop was: the retarder manual switch+→ retarder manual switch 1 → retarder control relay 1 → I relay → M (bonding), 1 energising work of retarder body.
When switch was in 2 gears, control loop was: the retarder manual switch+→ retarder manual switch 1,2 → retarder control relay 1,2 → I, II relay → M (bonding), 1,2 energising work of retarder body.
When switch was in 3 gears, control loop was: the retarder manual switch+→ retarder manual switch 1,2,3 → retarder control relay 1,2,3 → I, II, III relay → M (bonding), 1,2,3 energising work of retarder body.
When switch is in 4 gears, control loop is: the retarder manual switch+→ retarder manual switch 1,2,3,4 → retarder control relay 1,2,3,4-I, II, III, IV relay → M (bonding), 1,2,3,4 energising work of retarder body.
(2) retarder brake controller: retarder is worked automatically, braked the control of switch S 10.
When chaufeur is stepped on brake pedal, S10 closure, the K6 closing of contact, 6 of retarder brake controllers have, then 1,2,3,4 of retarder brake controllers according to this electric, make retarder control relay I, II, III, IV closed according to this, thereby make retarder body energising work.Its time gap is 0.25s.
The utility model circuit has the following advantages: can be connected with available circuit is supporting well, not influence the normal operation of other electric system; The change amount is little, can guarantee the unitarity of existing product; Simple to operate, can reduce driver fatigue intensity.Use the auxiliary braking system of current vortex retarder of the present utility model, can improve braking ability, safety, the traveling comfort of automobile, prolong the service life of brake strip.

(5) specific embodiment
Be depicted as the specific embodiment that the utility model is used for the Steyr automobile as Fig. 1-4
1. with current vortex private siding bundle one cover, its concrete body harness figure as shown in Figure 2, the chassis harness diagram as shown in Figure 3, the body harness diagram as shown in Figure 4.
2. eddy current retarder and relevant supporting control apparatus spare one thereof overlap.
3. to select capacity for use be on the 180A.h two to battery.
4. to select nominal power for use be 3kw to electrical generator.
5. will deduct 240mm with retarder bonded assembly transmission shaft axial length, all the other require constant.
6. retarder auxiliary stand one cover can be used Steyr IS991590203 sub-component.
Claims (2)
1. plant the heavy motor vehicle complemental brake system, it is characterized in that: on the transmission shaft of heavy motor vehicle, be connected with current vortex retarder.
2. heavy motor vehicle complemental brake system according to claim 1 is characterized in that: described current vortex retarder includes automatic control circuit and manual control circuit.
