Abstract
The utility model provides a combined type motorcycle frame, which comprises a frame head vertical tube (1), an upper beam frame (2), a lower beam frame (3) and an engine mounting bracket (4). The engine mounting bracket (4) is an independent component which is fabricated separately and then connected to the upper beam frame (2) and the lower beam frame (3) respectively through fastening pieces (7), so as to form a complete motorcycle frame. The engine mounting bracket (4) is an independent component which can be conveniently disassembled, assembled and adjusted, so as to improve the generality and exchangeability of the frame and the replaceability of the components. The non-welding connection manner of the engine mounting bracket (4) which is the most important stress complex component is helpful for reducing residual stress and deformation. Moreover, the engine mounting bracket (4) can be fabricated by adopting the materials with better properties, so as to simplify the structure thereof and improve the individuality of a motorcycle, thereby improving the grade of the motorcycle product.
Description
Technical field
The utility model relates to a kind of frame of motorcycle, particularly a kind of combined motorcycle vehicle frame.
Background technology
As everyone knows, vehicle frame is an important spare part of motor bike, be mainly used in and hang driving engine, seat saddle, fuel tank, bumper and wheel or the like, and bear motive power and the impulsive force that driving engine and tire pass over, so the quality of its performance directly has influence on the quality of motor bike.At present, the main body of vehicle frame of motor bike (except tailstock and the back chain stay) is essentially the one-piece construction that welds out with same material, and its rigidity and intensity are all fine, and manufacture craft is also fairly simple.But, the integral type welded frame also has defective, is mainly reflected in the following aspects: at first, the integral type welded frame belongs to non-dismountable structure, be difficult to adjust its size and position, greatly limited the convertibility of commonality, interchangeability and the parts of vehicle frame; Secondly, the integral type welded frame is because the welding influence often has bigger unrelieved stress, more easily cracks and is out of shape, thereby have influence on the safety and the reliability of motor bike; At last, because present welding conditions limits, difficult two and plural metallic material are carried out the failure-free weld together, therefore there is the motor bike of special requirement can not satisfy its personalized needs for some, such as just need vehicle frame for some cross-country motorcycle at the position that driving engine is installed, resemble engine mounting bracket, just need other parts of intensity ratio vehicle frame higher, this moment, then vehicle frame can become complicated and too fat to move if only want to go to consider to strengthen from configuration aspects by not changing with material.
Summary of the invention
The deficiency that the utility model exists at existing unit frame, a kind of combined motorcycle vehicle frame is provided, its purpose is effectively to improve the convertibility of commonality, interchangeability and the parts of vehicle frame, the distortion and the stress of the former thereby generation of welding reduces vehicle frame simultaneously because can also carry out the personalized material of using to the vehicle frame different parts in addition easily.
For achieving the above object, the technical solution adopted in the utility model is: a kind of combined motorcycle vehicle frame is provided, this vehicle frame comprises headstock standpipe, last roof beam structure, lower beam frame, engine mounting bracket, tailstock and back chain stay, it is characterized in that described engine mounting bracket is a separate piece, this member employing rivet or bolt structure and last roof beam structure and lower beam frame are fastenedly connected, and become the combined motorcycle vehicle frame.
Be fastenedly connected with last roof beam structure and lower beam frame etc. again after a kind of combined motorcycle vehicle frame of the utility model adopts engine mounting bracket to make separately and be assembled into vehicle frame, because engine mounting bracket can be dismantled easily, installs and adjust, therefore improved the convertibility of commonality, interchangeability and the parts of vehicle frame; In addition, because engine mounting bracket is important stressed complicated part, it adopts the mode of non-welding to be connected with and is beneficial to and reduces unrelieved stress and distortion; At last, engine mounting bracket can adopt the performance better material to make such as corrosion-resistant steel, titanium alloy steel, aluminum alloy and other alloy steels etc., therefore can effectively simplify its structure on the one hand, the personalization that can also increase motor bike is on the other hand expressed, thereby promotes the class of motorcycle product.
Description of drawings
Fig. 1 is the front view of an embodiment of a kind of combined motorcycle vehicle frame of the utility model;
Fig. 2 is the right elevation of a kind of combined motorcycle vehicle frame shown in Figure 1;
Fig. 3 is the front view analogous diagram of a kind of combined motorcycle vehicle frame shown in Figure 1.
The specific embodiment
Fig. 1, Fig. 2 and Fig. 3 show front view, right elevation and the front view analogous diagram of an embodiment of a kind of combined motorcycle vehicle frame of the utility model respectively.In this embodiment, described frame of motorcycle comprises headstock standpipe 1, last roof beam structure 2, lower beam frame 3, engine mounting bracket 4, tailstock 5 and back chain stay 6; Wherein engine mounting bracket 4 is an individual member, and this member is connected respectively to roof beam structure 2 and lower beam frame 3 by fastener 7 after making separately again, thereby is assembled into a complete frame of motorcycle; Need to prove, fastener 7 has several, can be that rivet also can be screw or bolt, engine mounting bracket 4 can adopt than headstock standpipe 1, go up institute's materials better material such as roof beam structure 2 and lower beam frame 3 such as corrosion-resistant steel, titanium alloy steel, aluminum alloy and other alloy steels etc. are made.
In the present embodiment, because engine mounting bracket 4 is an individual member, it can be dismantled easily, installs and adjust, and has therefore improved the convertibility of commonality, interchangeability and the parts of vehicle frame; In addition, because engine mounting bracket 4 is important stressed complicated parts, it adopts the mode of non-welding to be connected with and is beneficial to and reduces unrelieved stress and distortion; At last, engine mounting bracket 4 can adopt the performance better material to make, and therefore can effectively simplify its structure on the one hand, and the personalization that can also increase motor bike is on the other hand expressed, thereby promotes the class of motorcycle product.
