Abstract
The utility model discloses a AMT uses bonnet bolt, including the bolt body, bolt screw in upper cover and transmission housing's external screw thread (1) and external screw thread (4) that fixed pencil checkpost was used are offered respectively to the both ends of this bolt body, and the centre of bolt body is provided with hexagon head (2) and location boss (3). During the user state, upper cover (6) and last bonnet bolt pass through external screw thread (1) threaded connection of bolt screw in upper cover and transmission housing, external screw thread (4) threaded connection that pencil checkpost (5) were used through the fixed pencil checkpost of nut (7) and last bonnet bolt. The utility model is used for at installation, the maintenance in -process of pencil, need not dismantle the bonnet bolt to furthest has guaranteed the gas tightness of gearbox. And through the rational design for the pencil is direct with the upper cover contact to take place, when the transmission housing temperature is higher, can obviously not shorten the life of pencil insulating layer.
Description
Technical field:
The utility model relates to a kind of bolt, is specifically related to a kind of AMT bonnet bolt.
Background technique:
In commercial car AMT field, the AMT actuator that external many employings are integrated, gear shifting actuating mechanism and gearbox mechanical part are integrated, reliability is higher, but cost is also higher simultaneously.Domestic AMT many employings split-type design, be arranged in the diverse location on gearbox by gas circuit, wire harness, gear shifting actuating mechanism etc., reduce cost, but simultaneously because parts are more, need the position of reasonable Arrangement gas circuit, wire harness etc., to meet the requirement such as installation, use, maintenance of AMT.
The current AMT product of certain company all have employed split-type design, and gas circuit, wire harness, gear shifting actuating mechanism etc. are arranged in the diverse location on gearbox.Wire harness is fixed on and covers by current use wire harness clip, traditional hexagon head bolt is used owing to covering on current, dismounting is needed during fixed beam clamp, and use at the gearbox in later stage, in maintenance process, if desired wire harness is overhauled, when safeguarding, also need to dismantle bonnet bolt, this will greatly affect the tightness of gearbox, cause gearbox leakage of oil, and because wire harness itself contacts with upper cover, when gearbox works under extreme operating condition, transmission housing temperature is very high, wire harness can cause the isolation layer aging speed of wire harness to be accelerated with direct contact of upper cover of speed changing box, shorten the working life of AMT wire harness.
Model utility content:
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of AMT bonnet bolt.
For achieving the above object, the utility model adopts following technological scheme to be achieved:
A kind of AMT bonnet bolt, comprises bolt body, and the two ends of this bolt body offer bolt respectively and screw in upper cover and the outside thread of gear box casing and the outside thread of fixed beam clamp, and the centre of bolt body is provided with hexagon head and positioning boss.
The utility model further improves and is, hexagon head screws in externally threaded one end of upper cover and gear box casing near offering bolt.
The utility model further improves and is, positioning boss is near the externally threaded one end offering fixed beam clamp.
The utility model further improves and is, during using state, upper cover screws in upper cover with upper bonnet bolt by bolt and is threaded with the outside thread of gear box casing,
The utility model further improves and is, also comprises nut, and during using state, wire harness clip is threaded by the outside thread of nut with the fixed beam clamp of upper bonnet bolt.
The utility model further improves and is, it is identical or different with the outside thread nominal diameter size of fixed beam clamp from the outside thread nominal diameter of gear box casing that bolt screws in upper cover.
The utility model is used in the installation, maintenance process of wire harness, does not need to dismantle bonnet bolt, thus ensure that the tightness of gearbox to greatest extent.And by appropriate design, make wire harness directly and upper cover come in contact, when transmission housing temperature is higher, obviously can not shorten the working life of wire harness isolation layer.
Accompanying drawing illustrates:
Fig. 1 is the wire harness clip means of fixation schematic diagram adopted at present, and clamp is directly fixed on by upper bonnet bolt and covers.
Fig. 2 have employed AMT bonnet bolt of the present utility model and fixes wire harness clip.
Fig. 3 is the schematic diagram of a kind of AMT of the utility model bonnet bolt.
In figure: 1 screws in the outside thread of upper cover and gear box casing for bolt, and 2 is hexagon head, and 3 is positioning boss, 4 outside threads that are fixed beam clamp, 5 is wire harness clip, and 6 is upper cover, and 7 is nut.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3, a kind of AMT bonnet bolt of the utility model, the two ends of this bolt body offer bolt respectively and screw in upper cover and the outside thread 1 of gear box casing and the outside thread 4 of fixed beam clamp, and the centre of bolt body is provided with hexagon head 2 and positioning boss 3.Wherein, hexagon head 2 screws in one end of the outside thread 1 of upper cover and gear box casing near offering bolt, the close one end offering the outside thread 4 of fixed beam clamp of positioning boss 3.
During using state, upper cover 6 screws in upper cover with upper bonnet bolt by bolt and is threaded with the outside thread 1 of gear box casing, and wire harness clip 5 is threaded by the outside thread 4 of nut 7 with the fixed beam clamp of upper bonnet bolt.
When using Novel upper cover bolt, as indicated with 2,1 part will screw in gear box casing, upper cover and gear box casing are coupled together, the effect of 3 part boss is, the layout height of wire harness on gearbox can being limited, when designing the height of this part boss, having considered because wire harness distortion is rear and the factor such as distance, the length of wire harness, minimum radius bend of upper cover of speed changing box.When installing, overhauling wire harness, without the need to dismantling upper bonnet bolt, only need as above shown in Fig. 2, to dismantle nut, the dismounting of wire harness clip 5 and wire harness can be completed, the wire harness clip means of fixation adopted at present in relative Fig. 1, the AMT Novel upper cover bolt adopting the utility model to provide can not affect the tightness of gearbox.
