Technical field
The utility model relates to a kind of power actuated vehicle, and the single-point that is specifically related on a kind of power actuated vehicle hangs.
Background technology
Single-point on the existing vehicle hangs and by clevis bolt and leaf spring permanent seat leaf spring is fixed on the axletree, in actual applications, there is the phenomenon of left and right sides play in leaf spring during single-point hangs, the as easy as rolling off a log heel and toe wear that causes the tire part of leaf spring of play takes place, and makes travelling of vehicle bring certain potential safety hazard.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of fixing single-point of pin that has of left and right sides play that can effectively prevent to hang.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Having the fixing single-point of pin hangs, include leaf spring, train wheel bridge, leaf spring backing plate, clevis bolt and leaf spring permanent seat, the two ends of described leaf spring are located on the leaf spring backing plate, the leaf spring backing plate is located on the train wheel bridge, train wheel bridge is located on the axletree, the leaf spring permanent seat is located at the top at the two ends of leaf spring, and clevis bolt passes the leaf spring permanent seat leaf spring is fixed on the axletree, is provided with the set pin that prevents leaf spring left and right sides play in the described leaf spring.
Be respectively equipped with corresponding positioning hole on described leaf spring backing plate and the leaf spring, described set pin is located in the described knock hole, and described leaf spring backing plate is captiveed joint with train wheel bridge, as adopting the type of attachment of welding.
Be respectively equipped with corresponding positioning hole on described leaf spring backing plate and the leaf spring, described set pin is located in the knock hole of leaf spring backing plate and leaf spring, and an end of set pin is captiveed joint with the plate face of train wheel bridge, for example adopts welding or integrated version.
Described leaf spring, leaf spring backing plate and train wheel bridge are respectively equipped with corresponding positioning hole, and described set pin is located in the described knock hole.
The beneficial effects of the utility model are: because on the basis of original fixed form, set up the fixing version of pin, effectively prevented the phenomenon of leaf spring left and right sides play, avoided because of leaf spring left and right sides play, the situation of the local heel and toe wear of the tire that causes, got rid of existing existing potential safety hazard, made it more safe and reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of embodiment one of the present utility model;
Fig. 2 is the enlarged drawing at A shown in Figure 1 place;
Fig. 3 is the structural representation of embodiment two of the present utility model;
Fig. 4 is the enlarged drawing at B place shown in Figure 3.
Among the figure: 1, axletree; 2, train wheel bridge; 3, leaf spring backing plate; 4, leaf spring; 5, set pin; 6, clevis bolt; 7, leaf spring permanent seat; 8, knock hole.
The specific embodiment
Embodiment one: as shown in Figure 1, 2, having the fixing single-point of pin hangs, include leaf spring 4, train wheel bridge 2, leaf spring backing plate 3, clevis bolt 6 and leaf spring permanent seat 7, the two ends of described leaf spring 4 are located on the leaf spring backing plate 3, leaf spring backing plate 3 is located on the train wheel bridge 2, train wheel bridge 2 is located on the axletree 1, leaf spring permanent seat 7 is located at the top at the two ends of leaf spring 4, clevis bolt 6 passes leaf spring permanent seat 7 leaf spring 4 is fixed on the axletree 1, described leaf spring 4, leaf spring backing plate 3 and train wheel bridge 2 are respectively equipped with corresponding positioning hole 8, and described set pin 5 is located in the described knock hole 8.
Embodiment two: as Fig. 3, shown in 4, having the fixing single-point of pin hangs, include leaf spring 4, train wheel bridge 2, leaf spring backing plate 3, clevis bolt 6 and leaf spring permanent seat 7, the two ends of described leaf spring 4 are located on the leaf spring backing plate 3, leaf spring backing plate 3 is located on the train wheel bridge 2, train wheel bridge 2 is located on the axletree 1, leaf spring permanent seat 7 is located at the top at the two ends of leaf spring 4, clevis bolt 6 passes leaf spring permanent seat 7 leaf spring 4 is fixed on the axletree 1, be respectively equipped with corresponding positioning hole 8 on described leaf spring backing plate 3 and the leaf spring 4, described set pin 5 is located in the described knock hole 8, and described leaf spring backing plate 3 adopts the type of attachment of welding with train wheel bridge 2.Certainly, also an end of set pin 5 can be captiveed joint with the plate face of train wheel bridge 2, for example adopt welding or integrated version.This set pin has effectively prevented the problem of leaf spring left and right sides play.
Principle of work: there is a concave surface train wheel bridge 2 its bottom surfaces on the existing axletree, be fastened on the axletree by concave surface, so train wheel bridge is axletree left and right sides play relatively not, the mounting means of set pin adopts above-mentioned two embodiments, as long as by set pin leaf spring is fixed on the train wheel bridge, just can prevent the left and right sides play of leaf spring.
In a word; though the utility model has been enumerated above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
