Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to a motorcycle throttle assembly with an intake manifold. Background Art

[0002] The position of the motorcycle intake manifold is between the throttle and the engine intake valve. This component plays an important role in the motorcycle's intake system. The intake manifold is a pipe connecting the air filter to the cylinder head valve. It can be vividly compared to an adult's respiratory tract. Its function is to maintain driving safety. The design and position of the intake manifold are crucial to ensure the normal operation and performance of the motorcycle engine.

[0003] The intake manifold and the throttle valve are often connected by flanges or other means, and there are certain problems with their airtightness. After the intake manifold is installed on a motorcycle, it is difficult to detect the sealing between the intake manifold and the throttle valve on the motorcycle after it is connected to the throttle valve through the flange, which will directly affect the performance of the engine and easily cause faults such as unstable idling, weak acceleration, and insufficient engine power. Therefore, an intake manifold and motorcycle throttle valve assembly structure with good airtightness is proposed, which can be tested for airtightness before installation, is easy to detect, and avoids adverse effects on engine performance. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a motorcycle throttle assembly with an intake manifold and good air tightness.

[0005] The technical scheme is as follows: A motorcycle throttle assembly with an intake manifold comprises a throttle and an intake manifold, the main points of which are that a connecting rubber sleeve is arranged between the throttle and the intake manifold, the connecting rubber sleeve is threadedly connected to the throttle and the intake manifold, one end of the connecting rubber sleeve is sleeved on the inlet end of the intake manifold, and the other end is sleeved on the outlet end of the throttle;

[0006] A sealing strip protruding inward is arranged in the middle of the connecting rubber sleeve, and the throttle valve and the intake manifold are butted against each other with a gap therebetween, and the sealing strip can be inserted into the gap.

[0007] With the above structure, the connecting rubber sleeve connects the throttle valve and the intake manifold into a whole, which is convenient for detection and can be tested for air tightness before installation. The rubber sleeve has better machinability and small size. The sealing strip can better seal the throttle valve and the intake manifold to avoid leakage from the gap between the two. It has good sealing performance and can effectively solve the leakage caused by poor assembly at the customer's place. At the same time, with the help of the softness of the rubber sleeve, the impact force between the throttle valve and the intake manifold can be reduced, and the assembly difficulties caused by errors in various installation dimensions can also be reduced.

[0008] Preferably, an unclosed annular clamp groove is provided on the outside of the connecting rubber sleeve, and two fixing rings are provided at both ends of the unclosed annular clamp groove, with a certain gap left between the two fixing rings. With the above structure, the annular clamp groove can protect the inner connecting rubber sleeve, and at the same time, by providing a fixing structure in the fixing ring, the annular clamp groove is fixed to the outside of the connecting rubber sleeve.

[0009] Preferably, a fixing block is transversely arranged in the fixing ring at both ends, the fixing block is cylindrical, a through hole is transversely arranged in the middle of the fixing block, the through hole is directly opposite to the gap between the two fixing rings, and a long screw is passed through the through hole. With the above structure, the fixing block and the long screw cooperate with each other to jointly ensure a stable connection between the annular clamp groove and the connecting rubber sleeve.

[0010] Preferably, a protective sheet is arranged on the outside of the connecting rubber sleeve, and the protective sheet is located at the unclosed part of the annular clamp groove and on the inner side of the fixing block and the long screw. With the above structure, the setting of the protective sheet makes up for the unclosed part of the annular clamp groove, and cooperates with the annular clamp groove to protect the connecting rubber sleeve on the inside, avoiding friction with the outside world, causing displacement of the connecting rubber sleeve, etc.

[0011] As a preference: a limiting notch is provided on the connecting rubber sleeve, the limiting notch is close to one side of the throttle, the throttle is provided with a limiting block corresponding to the limiting notch, the limiting block protrudes upward and is provided above the throttle, and the limiting block can be correspondingly inserted into the limiting notch. With the above structure, the corresponding setting of the limiting block and the limiting notch can ensure the stability of the connecting rubber sleeve, limit the movement of the connecting rubber sleeve, and avoid displacement due to vibration during operation, thereby causing the rubber sleeve to fall off the throttle and cause adverse effects on the engine.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the integrated throttle is suitable for large-displacement motorcycles. The throttle and the intake manifold are connected by a rubber sleeve, which has better processability, small size, good sealing performance, and can effectively solve the leakage caused by poor assembly at the customer's place. On the other hand, the throttle and the intake manifold are connected by a rubber sleeve. With the help of the softness of the rubber sleeve, the impact force between the throttle and the intake manifold can be reduced, and the assembly difficulty caused by the error of each installation size can also be reduced.
