Abstract
The utility model discloses a saddle type draft gear of a heavy-duty combination vehicle. The saddle type draft gear of the heavy-duty combination vehicle mainly comprises a frame, a connecting support and a saddle. The connecting support is arranged on the end portion of the frame in a matching mode. The saddle is far away from the frame and arranged on the connecting support in the matching mode. The saddle type draft gear of the heavy-duty combination vehicle is capable of overcoming the defects in the prior art that the connecting interval is big, abrasion is serious, safety is poor, adaptability to the road surface is poor and service life is short, and therefore the saddle type draft gear of the heavy-duty combination vehicle is capable of eliminating the connecting interval, reducing abrasion, improving connecting reliability and safety, improving adaptability to the road surface and prolonging service life.
Description
Technical field
The utility model relates to vehicle tractor equipment technical field, particularly, relates to a kind of Heavy Duty Truck cradle type draw gear.
Background technology
Traditional train-type vehicle hook ring type and bolt-type draw gear are that vehicle frame tail boom and hauling hook connect as one.This connection mode can realize the purpose that main car is connected with trailer.
But, be direct pulling force because the hauling hook of this draw gear is subjected to, and this power is directly to be delivered on the captive nut of hauling hook, the hauling hook captive nut that draw gear therefore easily occurs lost efficacy.In addition, this draw gear and tractor truck connect with eye hitch, and there is very large gap the junction, drive at main car and easily rock in the trailer traveling process and send the noise of bang bang, quick-wearing very when under tension and impulsive force causes that service life is short, result of use is bad.
In realizing process of the present utility model, the defective such as the contriver finds to exist at least in the prior art that joint gap is large, serious wear, poor stability, road surface bad adaptability and service life are short.
Summary of the invention
The purpose of this utility model is, for the problems referred to above, a kind of Heavy Duty Truck cradle type draw gear is proposed, with realize eliminating joint gap, reduce to wear and tear, improves the reliability of connection and safety, raising road surface comformability and the advantage that increases the service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Heavy Duty Truck cradle type draw gear, mainly comprise vehicle frame, cooperate the connection bracket that is installed in described vehicle frame end, and be installed in the saddle on the described connection bracket away from vehicle frame, cooperation.
Further, between described saddle and connection bracket, be provided with for the up and down movable attaching parts of saddle.
Further, described movable attaching parts comprises the hinge seat that is installed between described connection bracket and the saddle, and cooperates the axle of installing with described hinge seat.
Further, described connection bracket is fixedly mounted on the vehicle frame end by bolt or rivet.
The Heavy Duty Truck cradle type draw gear of each embodiment of the utility model owing to mainly comprising vehicle frame, cooperates the connection bracket that is installed in the vehicle frame end, and is installed in the saddle on the connection bracket away from vehicle frame, cooperation; Can eliminate the gap between connecting device, so that the wearing and tearing that the pulling force in the actual use procedure and impulsive force cause reduce to minimum, improve simultaneously safety, the road surface comformability is stronger, and greatly prolong service life; Thereby the defective of can overcome that joint gap in the prior art is large, serious wear, poor stability, road surface bad adaptability and service life are short etc., with implementation structure simple compact, wearing and tearing are little, safety good, the road surface comformability is good and the advantage of long service life.
Other features and advantages of the utility model will be set forth in the following description, and, partly from specification sheets, become apparent, perhaps understand by implementing the utility model.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification sheets, is used from explanation the utility model with embodiment one of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model Heavy Duty Truck cradle type draw gear;
Fig. 2 is the local structure schematic diagram of the utility model Heavy Duty Truck cradle type draw gear;
Fig. 3 and Fig. 4 are the structural representation that the utility model Heavy Duty Truck cradle type draw gear is in the different operating state.
By reference to the accompanying drawings, Reference numeral is as follows among the utility model embodiment:
The 1-vehicle frame; The 2-connection bracket; The 3-saddle.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
According to the utility model embodiment, provide a kind of Heavy Duty Truck cradle type draw gear.Such as Fig. 1-shown in Figure 4, the present embodiment mainly comprises vehicle frame 1, cooperates the connection bracket 2 that is installed in vehicle frame 1 end, and away from vehicle frame 1, cooperate the saddle 3 that is installed on the connection bracket 2.
During implementation, between above-mentioned saddle 3 and connection bracket 2, be provided with for the up and down movable attaching parts of saddle 3.This movable attaching parts comprises the hinge seat that is installed between connection bracket 2 and the saddle 3, and cooperates the axle of installing with hinge seat.Above-mentioned connection bracket 2 can be passed through bolt or rivet, is fixedly mounted on vehicle frame 1 end.
The Heavy Duty Truck cradle type draw gear of above-described embodiment is the draw gear of a kind of main tailstock section, mainly is comprised of vehicle frame 1, connection bracket 2, saddle 3, and vehicle frame 1, connection bracket 2 and saddle 3 cooperate installation successively; Purpose is in order to eliminate the gap between connecting device, so that the wearing and tearing that the pulling force in the actual use procedure and impulsive force cause reduce to minimum, has improved simultaneously safety, and the road surface comformability is stronger, and greatly prolong service life; Have the characteristics such as simple and compact for structure, that wearing and tearing are little, safety performance good, the road surface comformability is stronger, greatly prolong service life.Simultaneously, the saddle 3 in this draw gear is compared with traditional saddle, and upset (can referring to Fig. 3 and Fig. 4) angle increases, so that the result of use of whole draw gear is better.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
