Abstract
The invention discloses an assembling part structure of driving shaft middle bearing in the back-wheel driving automobile (RDW), which is characterized by the following: transmitting motor power to back wheel through driving shaft, forming channel along longitude direction of automobile in the center of middle floor, allocating middle bearing and assembling rack in the channel, forming bag-shaped flute on the assembling rack, forming sealed box with channel, allocating nut with pipe in the bag-typed flute.
Description
Technical field
The present invention relates to a kind of structure that is used to strengthen the local stiffness of front engine rear drive formula (FR) vehicle.More specifically, the present invention relates to a kind of structure of rigidity of the mounting portion that is used to strengthen cardan shaft center bearing.
Background technology
Front engine rear drive formula (FR) vehicle should have a transmission shaft, is delivered on the diff of back in order to the propulsive effort with driving engine.Usually a middle bearing is equipped with in the centre of transmission shaft so that support by the centre portion of the intermediate floor of vehicle body.
Therefore, the structure of the mounting portion of the middle bearing of intermediate floor and adjacent part thereof should be designed to have enough rigidity, to stand to be passed to by transmission shaft the vibration or the disturbance force (to cause vibration) of vehicle body.
Summary of the invention
Embodiments of the present invention are used to improve the rigidity of the mounting portion of cardan shaft center bearing, thereby improve the durability of vehicle and reduce its noise.
A kind of structure of using the mounting portion of the cardan shaft center bearing in the rear-wheel drive vehicle (RWD) that transmission shaft is delivered to engine power trailing wheel, it comprises: one at the middle part of intermediate floor along the passage of vertical formation of vehicle; An assemble frame that is provided in the passage and is assembled together with middle bearing; Be formed on the bag shape groove on the assemble frame, forming closed box body, and in bag shape groove, be equipped with a pipe nut with passage.
Preferably, the bag shape groove of assemble frame is equipped with a dividing element, so that bag shape groove can have a dual separation structure.In addition, preferably, thereby a bracing bars couples together the both sides of assemble frame and crosses passage.
Description of drawings
In order to understand essence of the present invention and purpose better, reference should be made to the following detailed description taken in connection with the accompanying drawings.Wherein:
Fig. 1 is the decomposition diagram of structure of the mounting portion of the cardan shaft center bearing that provides according to an embodiment of the invention;
Fig. 2 is the assembling perspective view of the structure of the mounting portion of the observed cardan shaft center bearing that provides according to an embodiment of the invention from the bottom;
Fig. 3 is the sectional elevation of structure of the mounting portion of the cardan shaft center bearing that provides according to an embodiment of the invention; And
Fig. 4 is the sectional elevation of the structure of the diagram mounting portion that shows the cardan shaft center bearing that provides according to an embodiment of the invention.
The specific embodiment
Referring to figs. 1 through 4, intermediate floor 100 in the middle along vehicle vertically be formed with a passage (T), a transmission shaft (S) passes from the inside of passage (T).
The middle bearing (C) of transmission shaft (S) is fixed on the intermediate floor 100 by assemble frame 150, so that transmission shaft (S) is supported.
The upper surface of the passage (T) that forms at the middle part of intermediate floor 100 vertically is equipped with a strengthening part 120 along vehicle.Assemble frame 150 is installed in the installation site of middle bearing (C).One bracing bars 180 couples together the two ends of assemble frame 150 and therefore crosses passage (T).
Both sides are equipped with the crossbeam of front stall along the Width of vehicle on intermediate floor 100.This has improved transversely the rigidity of intermediate floor 100 at vehicle.
Assemble frame 150 forms the shape of a trapezoidal cross-section that projects upwards in the middle, in order to be embedded in the passage (T).Bilateral symmetry ground in trapezoidal top forms marsupial shape groove 152.The two ends of assemble frame 150 are equipped with the flange that is connected with intermediate floor 100 respectively.In this structure, the vertical of passage (T) intersected with vertically being perpendicular to one another in intermediate floor 100 of assemble frame 150.
Referring to Fig. 2, the middle bearing (C) of supporting shaft (S) is connected on the assemble frame 150 by tie bolt.The assemble frame 150 that stay 180 is installed couples together the two ends of passage (T).
When assemble frame 150 is installed to the inside of passage (T), bag shape groove 152 and passage
(T) inside forms the box-like space with closed cross-section.And, bag shape groove 152 is equipped with a pipe nut 160 in order to be connected with middle bearing (C), and a dividing element 170, it is divided into two spaces by the internal water level land with bag shape groove 152, has formed a dual spacer structure in the mounting portion of middle bearing (C).
This dual spacer structure has improved the rigidity of the mounting portion of middle bearing (C), thereby has reduced noise and vibration effectively.
Referring to Fig. 3 and 4, there is passage (T) that transmission shaft (S) therefrom passes to strengthen its rigidity by the strengthening part 120 and the assemble frame 150 of top that lays respectively at passage (T) and bottom.And, form marsupial shape groove 152 on the assemble frame 150, so as by with the internal connection of passage (T), bag shape groove 152 provides the box body structure of a closure.
Preferably, by dividing element 170 is installed in the horizontal direction, the inside of bag shape groove 152 can be divided into two compartments.The lower space of said structure is equipped with pipe nut 160.
Therefore, when the hold-down bolt that holds when tween drive shaft is connected with pipe nut 160, the space from the mounting portion to the vehicle interior by intermediate floor 100 and strengthening part 120 by dual isolation.
In addition, the both sides of passage (T) are coupled together by stay 180, therefore, have prevented any contraction and expansion by vibration or the passage (T) that causes of external load.
By aforementioned obvious, the both sides of the passage (T) that forms at the middle part of intermediate floor are linked together by stay, therefore, have prevented the pucker ﹠ bloat of passage, have reduced the local vibration of passage, and have improved the rigidity of the mounting portion of middle bearing.
For the local stiffness of the mounting portion of having improved middle bearing, therefore the assemble frame of a curved shape of installation below the front-row seats crossbeam forms box body respectively by the upper and lower surface on the floor, has improved the modulus of rigidity of above-mentioned mounting portion.
Therefore, intermediate floor passage of the present invention is strengthened by using dual separation structure and stay, causes the reduction of vehicle cabin noise and the improvement of vehicle durability.
